listening to MP3 windows media on bluetooth headset?

hi everyone. is it possible to listen to my windows media palyer mp3 and other audio in a bluetooth headset? i bought a BT headset and got it to wotrk on my xda2 for incoming and outgoing calls...but when i listen to my audio in windows mobile, the sound still comes out of the xda2...
i hope you guys have something for this...
thanks.

I have a PPC-6601 with the same issue. The platform apparently does not support "audio on demand" over bluetooth. There may be 3rd party software or a bluetooth stack tweak that fixes this but as of yet I have not found one. If it exists it is probably on this site, but I'm still searching.
Hopefully someone will post a fix.
This also causes voicecommand to not work over the bluetooth, which means that a wired headset is far superior to a bluetooth one on these phones. Hopefully it is not a hardware limitation.
good luck to us.

Its not a limitation... but the device should support AD2P profile... which is not still in there.. will will have to wait for it

Hey guys,
check out PDA2K_BroadcomCorp_BTUpdate.cab on this forum:
http://forum.xda-developers.com/viewtopic.php?t=14329
I believe this adds the AD2P and keyboard profiles to the phone. When I installed it on mine I saw a new profile for bluetooth high quality audio headphones. Unfortunately my bluetooth headset (Logitech mobile freedom) doesn't seem to support AD2P. I was hoping to get low quality audio on demand through the headset, not necessarily high quality audio. My goal is to get microsoft voice command to work over the bluetooth headset speaker and mic.
Let me know if you have any ideas for getting audio on demand over my bluetooth headset, and if you have a good set of bluetooth headphones that support AD2P, the file at the link above should get it working if you have the broadcomm/widcomm bluetooth stack.

Thanks for the link
Thanks for the link, will have to search for the update for PDA2k....

pda2k update
that file should work on any pda using the broadcomm bluetooth stack. it adds the high quality audio profile and keyboard profile.
i am looking for a way to get a headset profile to behave exactly like a wired headset. apparently this is not an option.

Hissing A2DP in WM6

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...

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.

A2DP Audio routing problems

Well, being that this is my first post, I would first like to say that this site and forums are top notch, I have had my 8525 for about a month now and have learned an immense amount of knowledge in a short amount of time thanks to you guys. Now for my problem...
I have my 8525 running Black Magik, radio 1.43.00 and have recently purchased a pair of Sony DR-BT21G A2DP stereo headphones. Now I was a bit weary about buying these since I have seen no mention of them on these forums... buy anyways. When I first paired the devices together I was able to listen to music without problem, though sound needed to be tweaked. After trolling for quite some time through the forums (yes, the search feature works great) I found what appeared to be the best A2DP setting for audio quality, and now after playing with every possibility cannot get music routed to the headset, phone calls work without a hitch. I have downloaded BTAudio to route all system sounds to the headset but It doesn't seem to work. I toggle BTAudio on and I can hear slight static through the phones but the audio still comes out through the system speaker. I have played with A2DP settings in both pimp my black and HTweakC but have not had any success. I am planning on reflashing Majik tonight to attempt to set it up from scratch, but I was wondering if anyone here could shed some light on this issue? Thanks in advance.

Delete the pairing. SR. Re-pair. Should do hte trick. Better yet - for the most stable ROM and A2DP tweaked for the best sound "out of the box" - reflash with Sleuth255 variant of LVSW ROM.

How exactly can I delete the pair? I can repair the device but have not seen an option to remove it?

To toggle Audio to A2DP you might want to see:

Another bluetooth question...

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!

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

Tweaking Bluetooth Stereo settings?

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?
