Thank you for all those superb WM6 upgrades.
I have one prob with all of them though. The Bluetooth A2DP gives a hissing sound. Using the Widdcom drivers or any of the registry improvements does not fix it. Downgrading to WM5 instantly solves the sound probs.
In WM5 changing from joint stereo to dual mono (in the registry) created the same problem, but changing the same entry in the registry does not work for me in WM6 (HTLM/software/microsoft/bluetooth/ad2p/settings/UseJointStereo).
Does WM6 always use dual mono or could something else be the problem?
Any suggestions are very welcome!
Any thoughts or suggestions would be greatly appreciated.
Thanx
Throw away your A2DP stuff buy a USB to 3.5mm converter with microphone and a good pair of wired stereo head phones.
I will definatly buy a converter as soon as I can find one that allows me to charge my phone and use the headphones at the same time.
Still, A2DP was working reasonably well for me on WM5, but it would be a shame to downgrade just for that.

Something like this maybe?
I'm using this one myself. With the longer wire to the 3.5mm plug it allows me to use my excellent SonyEricsson HPM-70 earplugs and HPM-85 cans.
the hissing sound has been mentioned many many times, search the forum for it.
There are no great solution to it, it depends on the headset, most headsets are not compatible with MS BT-stack
The solution : There are two ways to fix this, and it depends on which headset you are having,
1. You can try changing in the registry (find sleuths (?) post about a2dp fix )
you can also try my reg-fixes: http://forum.xda-developers.com/showthread.php?t=278778
2. You can install the Widcomm stack, (it can go along the ms btstack just fine) but it is not 100% stable and so on, it has absolutly stunning audio quality though.
I did search a lot before posting. It is not easy to find much about it.
Well there is 1 solution, WM5. That is what makes it so strange. WM5 sounds much better than WM6 and/or the Widcomm stack.
I don't understand how everyone keeps talking about the stunning quality of the Widcomm drivers. They sound much worse than the WM5 microsoft BT stack.
I think most of the talk about drop-outs has to do with the headsets. I've tried many of them and only the HTC has a good range and no dropouts (even when connected to my laptop).

well, that is because the widcomm stack is far superier in soundquality than ms. BUT it depends on the headset!
Different headset works better with different stacks!
one must try it out for himself!
What kind of headset do you have?
and wm6 (and ms) is not known for having a good a2dp stack at all. if it works in wm5 then maybe you should stick with wm5 instead of switching. I mean AKU 3.3.1 (or 3.3) is pretty good it is fast and stable, while wm6 is considered "beta"
I can't really think of any specifik features that wm6 offers that I MUST have. But I use it to try it, and I don't mind loosing data or so, and btw. I have a plantronic 260 headset and it is great with Widcomm but one can't stand listenening on it in wm5 or wm6 because of hissing and bad quality (even after all tweaks)
With Sleuths A2DP fix and the manual registry tweaking (HTCtweaker doesn't do it fully), I set bitpool etc to 52 and it sounds pretty nice on the HBH-DS970.
[HKLM/Software/Microsoft/Bluetooth/A2DP/Settings]
Value name=BitPool; Value data=52 (Decimal)
Value name=MaxSupportedBitPool; Value data=52 (Decimal)
Modify, Value name=UseJointStereo; Value data=0 (Decimal, Originally 1)
I tried almost all headsets. I can't remember that the results depended on the headset. All headsets had the same problem with WM6.
I do realize that my standards are probably too high and that no bluetooth will never do it. The Plantronics 260 is one of the few headsets that I didn't try. The 290 was a shock to me. Even wired the sound was absolutly awfull.
Even if the bluetooth is worse than WM5, WM6 has a number of features that are important to me. It is faster and definatly more stable on my phone. Most important however is that it has Voip built-in.
BTW the only headset that does a good job seems to be the HTC headset. It has a very good connection (up to a few meters), no drop-outs and you can connect your own headset to it, so it sounds reasonable. The difference in connection is not just with the HTC phones, but also on my laptop. A huge difference with any other headset I've tried.

Good 'phones
Have you tried using the audio enhancement feature of htweakc_2.0?
Also, the htc headset is based on the itech clip r35 and itech clip radio, I have the clip radio and it works wonders for a2dp on my TyTn and laptop. The secret is that they both use bluetooth 2.0 class 2 which is a perfect match for the hermes. although I can still hear that hissing on wm5 and 6. I thought they upgraded the bt stack in wm6?
also a good 3.5 mm/usb converter that is coming soon is the one for the p4350 which is a wired remote control/3.5 mm jack
http://www.expansys.com/htc/p_htc_item.aspx?i=145157
or tocharge and listen at the same time you just need a y cable
http://www.expansys.com/htc/p_htc_item.aspx?i=145068
I think I've tried every tweak here, including htweakc. I do not hear any difference. Is the hissing for you the same on WM5 and WM6? For me it is a huge difference (WM5 sounds much much better than any reg. hack or even the Widcomm drivers).
I did also try the itech clip (don't remember the type number) and that had the same great reception as the HTC. The advantage of the HTC is the 3.5 connector for you own headphone. Unfortunately both of them are bluetooth 1.2, which is a slight disadvantage.
The convertor is nice(and I'll probably get one), but I like to listen to music in bed and do not like having the phone under my pillow

Did you read my previous post? Did you try to manually edit registry as I wrote? Htweakc doesn't do it correctly.
Yes I did try those tweaks, but they do not change anything at all
As far as I can tell the A2DPfix is aimed at fixing the skipping problem. However when using the HTC headset I have no skipping at all. Not 1 single skip in over an hour listening! I did try the A2DP fix anyway with no result.
On WM5 changing the jointStereo setting to 0 would introduce the same hissing that I hear in WM6. Unfortunatly in WM6 changing from 0 to 1 and back doesn't make any difference.

you know, if you are not changing jointstereo in wm5 then you are not using stereo, then you could just use any monoheadset (as the sound would be the same)
jointstereo = 1 = mono (there are hissing, but it is hidden in low quality audio)
jointstereo = 0 = stereo (hissing is more "bad" because it uses twice as much bandwidth )
and all the other tweaks that are out there they work on wm5 ! (remember you have to soft reset your phone after regedit...(and before that you must wait around 15 minutes for wm5/6 to save your changes to rom before reset)
most of the fixes don't make so much changes in wm6 .
but widcomm should give you a real boost, are you sure you are pairing with the widcomm stack (high quality audio setting???)
Jointstereo is definatly not mono. It is the default setting in WM5 and it is indeed different from Dual mono (setting it to 1), but it is not mono.
You can hard reset your device (hold the power button a while) to have the settings written instantly to the rom.
I am sure that I am pairing with the Widcomm stack (high quality audio). It is indeed better, but defiantly not worth all the problems that come with it.

Just my two cents, I had hissing problem before and it was nothing to do with the Hermes but my headphones needed flashing. It's only for the Motorola HT820...
http://forum.xda-developers.com/showthread.php?t=276406&highlight=ht820+update
But as you say you have tried other headsets I guess this is not the problem
Also there is a guide that might be usefull...

To be honest I think the sound is great in WM6!
I've tried the Widcomm stack again. The sound improves a bit, though it still sounds like Beyonce has a speaking disorder
Unfortunately there is no hands-free (which is more important to me than audio) and occasional skipping is now introduced

I say damn! This worked totally perfect! At last I can use my Jabra bt620s for music as well.
Earlier I had the skipping prob., later (under WM6) the hissing prob - and now it's just clear pleasure.
Thanks a lot.

Have you (or anyone else in here) used the Jabra BT320s?? Its the same kind of thing as the HTC clip.?
Im looking for something along them lines but not sure if i want to spend as much on the HTC clip version.

I have Moto HT820 and JasJar with latest _official_ i-mate ROM. I applied the Tornado patch to get the Stereo Profile.
The sound works OK, except there is a lot of noise and distortion.
I've applied BitPool and SampleRate reg hacks but they dont seem to make any difference.
Anything else i can try?
Same here
I have a Motorola HT820 with my Qtek 9000 and the sound is really bad.
My friend has a Sony Ericson K800i and it works perfectly, the sound is great but with my Universal, the sound is very bad!!
Anyone has a trick or patch for A2DP?

try updating the firmware of your ht820 headset...the update is there in the forum..also, try using helmi's broadcomm stack http://forum.xda-developers.com/showthread.php?t=291639..works perfect with my uni+jabra bt620s

the update (which is at http://forum.xda-developers.com/showthread.php?t=276406 ; I've also linked in from my related article at http://forum.xda-developers.com/showthread.php?t=296770 ) will "only" fix the skipping problem; NOT the bad compatibility with the MS BT stack.
That is, the only way to fix the problem is 1, getting a compatible pair of headphones 2, changing the BT stack to Widcomm
see my post at
http://forum.xda-developers.com/showpost.php?p=1215382&postcount=133
in short, Widcomm is a bad choice for jasjar/HT820 headset.
At this point I think i fixed the quality (or got used to it), because i dont hear much difference when streaming music from PC vs jasjar.
The only BIG annoyance is the skips/pauses. Must be the damn phone doing something in the background!
Hi everyone. Not long time ago I bought T-mobile MDA Pro. I guess it's German version since it have QWERTZ keyboard layout.
It has some issues, but it was all software and I fixed it. But I have one problem that I couldn't solve my myself.
I have bluetooth headset Jabra BT620s. Bought it specially for using with my Universal (it's not handy to talk by phone with it in hands). Connected, added as Headset. Everything cool... have to be. But! It plays sound (as headset) this way: 1-2sec playing 30-40 sec silent. I didn't try hands-free because it have no use without listening to music. What had I try:
1. Different ROMS
- WM5 WWE 1.30.77 (if remember number right)
- WM6 J's WWE 2.02.02
- WM6 WWE 2.10.02
ALL ROMs had this issue
2. On every ROM I tried to change "priority" for A2DP (via RegEditor)
One thing helped me. Got broadcomm BT stack application (same was with WM5 ROM, but it seems different version). A2DP worked fine, hands-free too (as you remember I didn't try it without A2DP), BUT(!) all sounds via speakers and headphones (of course, when Jabra was offline) disappeared and my universal becon unresponsive and hanging up often. So I couldn't use it.
Maybe you can help me to solve the problem? Maybe I have to use different BT stack? Or try something with registry? Or... I have no idea.
And, by the way, does anyone knows which broadcom chip is used in Universal? Where can I get all specs (chipset e.t.c.)?
Thanks
Hi,
I had the same problem with my Universal and my Laptop too.
I thought it was a lack of memory problem but trying "light" player nothing changed...
I think that it could be related to pairing problems and the way Jabra BT620s activate BT profiles, because everything got solved restarting Jabra and activating Headset profile before the A2DP.
I solved definitely all the issues with Jabra BT620s using the new firmware with WM6 5.2.1413 and Microsoft Stack (with bitpool set between 30 and 36).
I hope being helpful.
Let me know if you have any interesting tricks...
Hi! Thanks for posting!
I forgot to write that I always trying to activate hands-free firs then headset. And all after powering on Jabra.
Ok. I tried to update firmware of jabra (as topic somwere nearby tells) and connect. Problem persists.
I'm not kinda pro in BT, so tell me what is _bitpool_? And how to set it?
I will google for sometime, of course, but if I won't find that, please, write. Does this mean to mess with registry?

That is in the Registry. I got the info from somewhere (Sorry cannot remember?) But I copied it to a text file, here it is: [HKLM/Software/Microsoft/Bluetooth/A2DP/Settings]
Add new dword, Value name=BitPool; Value data=48 (Decimal)
Modify, Value name=UseJointStereo; Value data=0 (Decimal, Originally 1)
For BitPool:
Microsoft suggests the following bitpool values for optimal buffer sizes.
30 - Low audio quality
40 - Medium audio quality
48 - High audio quality
58 - Excellent audio quality
Choosing 48 is adviced.
For UseJointStereo: use 0 instead of 1 else the streaming is done only in mono mode!
(I have a 8525 so AD2P came with it. I never added any entries I just changed the #'s. )
Gonna try it today, when back from work.
I understand that reducing quality gives better stability and performance. But I want true stereo, not joint.
Ideally I want get same sound as I'd have in wired headphones.
I have the same problem with this headset, after 6 hours testing, severals flashings with the best wm5&wm6 roms, i cant make it work!
Please help, i had changed the bitpool from 30 to 60, one up at a time (30,31,32...60) nothing happens.
I heard half sec music and then silence. WTF???
try to use widcomm stack. but the quality of music in mine headset using this stack is not very good. and there are some bugs such as no sound after disconnecting the jabra. if you find some solution, please post it here!
widcomm stack works great, finally after 6+ hours i heard sound from my headset! The sound is pretty good, also when i turn off the headset, the sound playback from the device.
f#ck you M$ with the crapy bt stack, i have lost half day.
Thank you l2tp.
Solved!
It was a bitpool. Little gude:
It was my WM6, so no keys were added.
Use registry editor
[HKLM/Software/Microsoft/Bluetooth/A2DP/Settings]
Value name=BitPool; Value data=48 (Decimal, Originally 30)
Value name=UseJointStereo; Value data=0 (Decimal, Originally 1)
Value name=MaxSupportedBitPool; Value data=500 (Decimail, Originally 30)
As I figured out, MaxSupp is some kind of "cache". When I tried 100, it became laggy after 30-40 minutes. But with 500 2hours played perfectly.
But! Have to solve 2 more problems:
1. Bad connection.
I'm carrying my Uni in bag and when comething getting in the way between bag and my head (i.e. my hand when I taking something form the bag) sound dissapears for 1-2-3 sec. It's not nice.
Maybe I should try widcomm stack? The question is where I can get it and what the type it should be? (don't post please "on widcomm site", give me as widcomm.com, I just can't search for now)
2. It's too quiet.
Wired headphones were pretty louder. Since I using subway 1.5 hours per day you can imagine that without 100% volume I can't hear the music normally.
I put Jabra on 100% and Uni 100% volume. But it like 50% of wired headphones' volume.
Should this be normal (Jabra less quiet), or can I do something?
YES! I know how it works, that Jabra have internal amplifier and BT signal decoder, but...
Of course, I don't wans to dissassemble Jabra and making hard additions to it (unless it will be a kind of volume regulator).
I need that Jabra played for nearly 5 hours. So I can spend attioional power of Jabra (in manual said that It can play for 14 hours, so I can get 195% boost in power).
Thanks everyone participated in this tread.
Argh! The M$ stack gives me creeps. Very unstable. It seems, that my Uni have not BT but some kinda radio transmitter back from WWII! Loosing signal in distance less than meter! I alwayes hated, will hate always M$ corp. OpenSource rules the world!

I cant understand why the p3300 works fine with jabra bt620s, and it has wm5.
I am still use broadcomm stack, not only works fine with bt620s, but also better with my gps receiver.

Thanks alot!
Ahem... On WM5 and shipped BT Broadcomm stack it still has bad connection!
I have asked this question in several other threads and have not recieved a response. I have also searched all threads within 1 week history for A2DP content and cant find my question answered anywhere... so here goes!!
Can people confirm their experiences with A2DP on the official Wm6 roms.
Does the skipping still occur with default rom settings?
Do you still have to install sleuths a2dp patch to get things anywhere near stable?
Is default sound quality good?
Is tweaking the bitpool and other reg settings still needed?
I have battled with all other roms and my Motorola Ht820 headset to get skip free good quality audio and never managed to get it working consitently and was waiting for the official WM6 roms to see if they would crack the issue?
All feedback appreciated.

I've had no problems with A2DP in the official Dopod WM6. it works great straight after install with no tweaks at all. It seems to be skip free and with good sound quality.
The only problem I still have (and had with every version & tweak) is playing m4a files with WMP. When playing these files, the phone goes back to the speaker...

Big A2DP User Here
I'm a big A2DP headset user when working out, so I have been keeping a close eye on the sound quality with the different WM6 ROM versions here. As posted before, the version from Sleuth was GREAT in sound quality.
The "official" WM6 ROM from HTC for Cingular/AT&T (US) does have the registry entry for UseJointStereo set to 1, so that is great. However, I did see that the MatBitRate and SampleRate were also there and set to 30. So, following the "best" settings on this forum, I deleted these two registry entries and added the increased rate entry of SampleRate at 48000.
The workout this morning sounded as sweet as with Sleuth's ROM.

Sounds promising, just gonna try my headset now with official dopod rom. Fingers crossed. What head set are you using?
I have a parrot hands free car kit and I find the quality is best when I just leave all settings as is. I think the a2dp on this rom sounds exceptionally weel.
I'm using the Motorola S9 headset.
I still have the skipping issue with Dopod SEA version and SE HBH-DS970. Before that I had one of LSVW's ROMs installed and AD2P used to work just fine in that rom.
yup, the dopod release does not seem to have all the fixes done here. i have tried LSVW and black and no more skipping issue with my DS970.

Hi, Was hoping that the patch that sleuth did (to fix the looping code error) would have been incorporated by M$ into the release. Looks as if it has not, which is a real shame. Just about to flash Black Satin and will try with and without Sleuths patch and post the results. Thanks for all the feedback guys, much appreciated.

check out the LAST LINE...
Advanced Audio Distribution Profile (A2DP)
This profile defines how high quality audio (stereo or mono) can be streamed from one device to another over a Bluetooth connection[1] - for example, music streamed from a mobile phone to a wireless headset.
A2DP was initially used in conjunction with an intermediate Bluetooth transceiver that connects to a standard output audio jack, encodes the incoming audio to a Bluetooth-friendly format, and sends the signal wirelessly to Bluetooth headphones that decode and play the audio. However, many Bluetooth 1.1, 1.2, and 2.0 mobile phones and portable media players natively support A2DP, and most newer Bluetooth 2.0 headphones support it as well.[2] Bluetooth headphones, especially the more advanced models, often come with a microphone and support for the Audio/Video Remote Control (AVRCP), Headset (HSP) and Hands-Free (HFP) profiles.
A2DP[3] is designed to transfer a 2-channel stereo audio stream, like music from an MP3 player, to a headset or car radio. This profile relies on AVDTP and GAVDP. It includes mandatory support for low complexity Sub Band Codec (SBC) and supports optionally: MPEG-1,2 Audio, MPEG-2,4 AAC and ATRAC, and is extensible to support manufacturer-defined codecs. Most bluetooth stacks implement the SCMS-T copyright protection. In these cases it is not possible to connect the A2DP headphones for high quality audio. E.g. the Motorola HT820 can be used for high quality audio only with certain versions of the Toshiba bluetooth stack.
HOPE THIS HELPS!!!!
Offical SEA WM6 ROM fixed all my A2DP issues with my BlueAnt X5 headsets. (No tweaks at all required)
One problem remainds... it pauses/skips if Wifi is left enabled. Not sure if that is a software or a hardware issue (both protocols use the same frequency)

Hi, thanks for the article, but dont think this is the problem as I am now getting a lot better A2DP support, no problem with playing the audio or the quality just the skipping. Nothing really has changed, it is a bit more stable but needs sleuths A2DP patch to make it usable. My point is that is sleuth could fix this with a bit of code at home (no offence sleuth) then could M4 not have used the might of their developmental skillset to fix this most annoying problem.
No Problems
I have been running the newest WM6 v3 rom from VP3G:

And I've been using A2DP without any skipping. I've been using an iTech clip headphone and it works great.

Same for me. With v3 of this ROM from VP3G, I get crystal clear STEREO sound thru my Motorola S9 headset.

I have asked this question in several other threads and have not recieved a response. I have also searched all threads within 1 week history for A2DP content and cant find my question answered anywhere... so here goes!!
Can people confirm their experiences with A2DP on the official Wm6 roms.
Does the skipping still occur with default rom settings?
Do you still have to install sleuths a2dp patch to get things anywhere near stable?
Is default sound quality good?
Is tweaking the bitpool and other reg settings still needed?
I have battled with all other roms and my Motorola Ht820 headset to get skip free good quality audio and never managed to get it working consitently and was waiting for the official WM6 roms to see if they would crack the issue?
All feedback appreciated.

1. Yes, I still got skipping after installing vp3G's v3.61 ROM.
2. So, yes, I installed Sleuth's A2DP patch.
3. That is all I did, and the sound is pretty good on my Motorola S805.
4. I haven't dome any registry tweaks, though I may to see if it makes any difference in sound quality.
Bluetooth stereo headset on htc s620?
Does anybody have expirience with a stereo bluetooth headset on de HTC S620 or Dash? and is this possible? And wich headset is a good one?
Fortunately, the Dash has bluetooth 2.0, so you'll be able to try the newer headsets/headphones as they come out. Sony has a set of 2.0 headsets that I tried as they had the earbud style I prefer (they stay in). The sound quality was a big disappointment though, not approaching that of wired headphones. The range was great though. Tried to watch video with them, but the audio was out of sync. Wound up returning them.
These look worth trying: http://mobilitytoday.com/news/007355/Jabra_BT8010_CES
Whatever you decide to try out, make sure the place you get them has a return policy.
Thanks for your reply.
i think i will keep it by mine wired headset
My dash was setup for poor audio on the stereo bluetooth. After much searching, i found out i had to delete the keys in the registry for it to work. Once i did that, audio quality improved ten times.
More on that here. I appear to not be the only one with the issue. If your getting poor audio quality with the stereo bluetooth, give it a shot.
I just got the itech clip headset which takes nomal earbud headphones not the headphones take look dorky when you wear them. A2DP AVCRP, works perfectly. No problems with audio quality. Handling of phone calls back to windows media player is fine Microsoft voice comand works fine as well. I have the o2 Germany ROM installed.
bluetooth headset profile question
everytime i connect my bluetooth headset or my wired handsfree headset my profile automatically changes to "headset" and i cannot change it to any other profile while the headset is connected
is there any way to change your profile while a headset is connected? or is there a registry edit that will do the job?
thanks in advance
Bluetooth loudness
Hi,
I am using the Dash flashed to the S620 original ROMs, on the US T-Mobile network.
Everything is fine, but the call volume on with my bluetooth headset seems low.
(I tried a Motorla hs500 and a samsung wep200)
Is there maybe a registry hack to increase the bluetooth volume?
Cheers,
Bela
I know what your talking about and I hate it. Only way to change the profile is to turn off your BT Headset.
I would like to have 2 headset profiles so i can have a silent one and that isnt silent.
bluetooth a2dp registry settings
So... following a thread here, I deleted everything in regards to those keys and I'm getting random dropouts whilst listening to music over my Motorola HT820 headphones. Is there anyway someone can send me their backup settings or tell me the settings so I can put them back in? Am I just forced to do a clean install of the WM6 Beta rom? I know, I'm stupid for not backing up, but they said it worked well... :-( Thanks!
HKLM\SOFTWARE\Microsoft\Bluetooth\A2DP\Settings
thats where the key values were deleted...
can someone give me their values so i can reprogram it in?! thanks!

bluetooth file exploring
is there any application or software that i can use to look at and copy files that are on other devices through bluetooth?
i used to have a samsung phone and i was able to do this, because my co workers and i always need files that are on eachothers phones and its just easier to go and get the file yourself then to have to ask them to beam me the files
any input would be helpful
T-mobile Dash and Bluetooth Stereo headphones
Has anyone tried using the A2DP functionality with bluetooth headphones to get stereo music? In particular I'm considering the I-tech S38 with my T-mobile Dash.
Thanks in advance!
My understanding is that certain headphones work better than others. Dishe over at HoFo tried the I-tech Clip r-35 with hs SDA and (I think) a Dash and wasn't happy with the results. I've used my cheapo Logitech BT headphones with my Dash and had very good results. Because of this I'd make sure whereve ryou get them has a liberal return policy.
Thanks for the update!
I followed up by searching the threads at Hofo and read a number of reviews outlining a bunch of issues with I-tech clips. Apparently, the plantropics headsets are much better.
cheers
My brother has a plantronics 590 I think it is. It sounded really good on my MDA, but that was before I had my dash.
None of them that I have tried (and I've tried a lot) sound nearly as good as a wired set of headphones. Definitely follow the poster's advice who recommended purchasing from someone with a return policy. I did, and returned them all -- an online store with a good selection and a good return policy: http://www.mobilecityonline.com
Bluetooth problem on SPV E600
Hi guys,
Anyone got that after installing HTC rom "RUU_Excalibur_HTC_WWE_1.11.405.4_4.1.13.28_02.63.90_Ship"?
I can't get the bluetooth to start.
Any help would be greatly appreciated

Same with t-mobile wm6 beta
Wololo,
I tried pairing up my Sony DS-980 stereo bluetooth headset with my Touch Pro 2. That worked flawlessly. I find the new bluetooth interface to be quite good. It has lots of fancy settings in a nice GUI.
BUT
When listening to music, the sound through my headset isn't very good. It sounds compressed and.. mediocre. I know it's not the headset, as it worked fine on my HTC P4350 (after some tweaking in the bitpool, that is).
I used to use Advanced Config for tweaking the bluetooth stereo settings. Apparently our Pro2 uses a new bluetooth stack which is not (yet) configurable through that program. I then tried searching for ways to edit the equivalent of the bitpool for our tp2's widcomm bluetooth stack. An old thread on xda stated 'Line Speed' to be the new 'bitpool' name. But that string is not in my registry. I might try adding it, but I doubt if that will work.
I also found 'Baudrate' as a candidate. but it's set to 4.000.000. That's quite high, in my idea.
Before I mess up my registry with 'playing around', does anyone know what else I can try? And am I the only one experiencing poor sound quality through stereo bluetooth?
Thanks!
Hi,
BT Stack on Rhodium is from Widcomm.
You can find the config in
HKLM\Software\Widcomm
I have not dug through to find ASDP settings, no time at the moment.
Please post back if you find it or not so that I can add them to the tweaks sticky.
Not sure if you have tried this or not, but with my car kit (which support HFP, A2DP and AVRCP I have to activate Stereo Audio on the Rhodium in BT Config, perhaps your headset behaves the same. If I do not audio is ****.
Cheers,
Beasty
OK, I think I got it. The Linespeed value does indeed seem to have an effect. I used this wiki as a guide:
http://wiki.xda-developers.com/inde...h your stereo Bluetooth headphones? Read this!
I used Resco Explorer Registry add-in to add the following DWORD value:
HKLM\Software\WIDCOMM\Plugin\AV\LineSpeed with a value of 320
That seems to do the trick. I'll test it for a bit, but I'm not experiencing drop-outs as of yet and my music sounds much better.
PS I first tried hacking around in the HKLM\Software\WIDCOMM\BTConfig\SerialTransport; increasing baudrate/bytesize values. Don't. Changing stuff breaks the bluetooth
yesterday i tested the a2dp range and it auto reduced quality the further i went. Unfortunately it did not vice-versa.
I'm going to test that reg.
EDIT: Definitely that reg works but it also makes the cpu use heavier and you notice that while using gps software on the car and streaming music. The 528mhz cpu is not powerful enough for this task. After some testing the value is like kb/s, so 272 is the usual for good quality, above that it takes allot of cpu. At the end i removed the reg because the device does the auto quality/cpu usage quite well. The quality is not quite the same has with a fixed value of 272 but barely worst.
Yeah, I noticed the same thing with the distance and quality, which kind of sucks as over time if the signal weakens for what ever reason (which will likely happen over an extended period of time) the audio quality gets worse and worse over time.
Also I have noticed that Audio controls don't seem to work on the TP2 with my BT stereo headphones (Sony DR-BT21G) and seem to play at max volume all the time. Not sure if this is something you guys have noticed as well or if it is specific to my head phones, though they have worked fine with other devices.
if you google it you will find ppl with dell and hp pda that uses/installed widcomm/broadcom stack and "unfortunately" it's a feature. The volume is controlled only by the a2dp receiver.
The linespeed does work but try and use wifi and a2dp at the same time You will get so much skipping :S My best experience is without that reg. Not the best quality but.. You will live with it.
Also it does adjust the "quality" itself. Lowers and uppers. It's just not instant.
anyone figure out the reg settings so it will force the call to use ringtone?
