The A2DP Thread, roms and headset. - P3600 ROM Development

I have a huge problem, there are so many roms available and the threads about them are so long. I was hoping to use this thread so people can write what rom and bluetooth headset they are using and how well a2dp i working. It would also be good if you could inform what the problem was: skipping, hissing sound, or so....
If you solved the problem using some editor or registry changes please write them down too.
For example:
I am using:
Rom:
[ROM][WWE][1.11.2008][UC] g77 5.20 OS CE 5.2.19971 AKU 1.2.6
Radio:
Radio 1.56.70.11
Headset
Sony Ericsson DS980 headset.
Result:
Unplayable, music skips all the time, song almost doesn´t play, jumps back an forth.
I have tried using Sleuth255´s a2dpfix and J.S. Advanced configuration tool with no success.

Plantronics 260 - no problems !!
Using same ROM as above (cME 0.9) with no fixes etc. - sound is clear and clean.
Coming to think about it - I never had A2DP related problems with this set with any 6.1 ROM (and I tried all of them - almost !!)

A2DP/AVRCP in Crossbow

Hello there.
I'm a newbie to using A2DP/AVRCP, sorry about that, but I have big issues.
I have huge lag when trying it out.
Specs:
HTC Universal
Midget's WM6 (Crossbow)
Radio 1.14
Bootloader 1.01?
Sony DR-BT20NX (really nice ones).
Anyways. I pair it up, no problemo at all. Tried a few calls. Works fine. Selected both handsfree and wireless stereo from profiles ofcourse.
So, I tried playing a movie in TCPMP. Audio and Video stutters every second. Tried playing a MP3 file in Media Player. Audio lag every second.
DAMN!
So, I went in to all these threads about A2DP/AVRCP in the forum (read them before) and checked out fixes etc. Everything seems to already be applied in this ROM. Priority256 value exists (in another folder though as described for another device, HKLM/BuiltIn/Drivers/WavDev I think)
What the heck can I do? I'm not comfortable applying different patches because I think A2DP support in every manner is already applied, so as the registry values.
HELP ME!!

Tried out BT Stack change for Hermes patch/program.
TEST RESULTS ON UNIVERSAL WITH WM6 (Midget aka Helmi unreleased)
Sound IS great. But other than that, this program does not work very well on my device. Of course this is designed for Hermes but I gave it a shot.
Issues:
1:
Screen flickers (only when this BT is turned on).
Flickers really bad and unable to use device.
Fix: set the device to standby (power button) and wake it up again. Flickering gone
2:
Once BT is deactivated for a few minutes I can't start it again.
Fix: No fix found yet. Only a Soft-reset and directly activate BT works.
3:
I can't use my GSM/UMTS connection anymore. Trying endlessly. Even after soft-reset's I can't connect. WiFi works fine though.
Fix: No fix found yet.
4:
Unable to uninstall this program. Tried several times. I get to the "Soft Reset Device Yes/Cancel". I soft reset, program still there and working.
5:
Hard-Reset, complete setup with WAP, MMS, MAIL etc.
Installed Widcomm BT Stack again.
Soft-reset:
Screen flickering (fix)
No 3G/UMTS connection avalible anymore. Even when BT stack is completly shut down.
We need a specific one for our Universal. Who's up to fixing this for us?
KEEPING this post updated.
EDIT 06: 18:40 @ 21/01/07
ANYONE into programming/developing interested in taking this as a sideproject so all of us Universal users can benefit from this great software?
PS. No, Nuclear (aka Infidel)! Pleace do not participate in other than testing. And if you do, please don't be too exited and write lies/bs in this thread. Thank you. Ta ta
I'm currently using Midget's WM6 with a set of Motorola HT820 bluetooth headphones without any problems.
In fact I've tried a couple of WM6 roms now and both have had working a2dp & avrcp and if anything quality is as good as the AKU3.3 I was previously running.
AVRCP & connecting up seems to be a little more reliable than the last rom as that would occasionally lose the pause control, something I don't think has happened on WM6 yet.
It might be worth trying your device with a different set of bt headphones to see if the problem persists.

Hmm. Headphones shouldn't matter, should it?? It's one thing if the sound in my headphones is bad, but it is the DEVICE that has problems actually outputting to the recoder fast enough. It works fine with the Widcomm!!

Did you need to do any extra tweaking on Midgets ROM to get them to work properly?

i've hs-12W. I'm using it with midget's first vanilla crosbbow rom without any problems. without any tweaking.
I have tried the broadcomm stack on WM6 but couldn't get my jabra bt620s stereo phones to connect to both the headset AND stereo profile at the same time - if I connected it to the stereo profile, then it sounded great, with no log, but wouldn't act as a headset. If I connect it as a headset, it works fine, but all audio is mono, even stuff that shouldn't be. Should I be able to get this working for both at the same time?
Worked straight away without needing any tweaking.
Both stereo & phone headset work okay.
Also had Stereo configured with Universal and Phone paired with a hermes since getting a second data SIM and that setup is working okay as well.

Is it true that this headset can store two pairing profiles (ie I can have them paired with my Qtek and my PC)?

A2DP with Official WM6 Roms

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.

Apply Sleuth's patch...
Did you apply Sleuth's patch? I wasn't sure if it would work on WM6 (official), but, thank goodness, it does! After 9 months I can listen to music!

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.
on a whim i knew what a2dp was but i just wanted to wiki it..
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.

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.

XDA IIs Stereo audio problem

Has anyone ever had anything like this problem?
I can not get my device (O2 XDA IIs) to output both channels of stereo audio.
I have upgraded the rom to what i thought was the latest (june 2005)
http://www.seeo2.com/user/XdaIIs/template/XdaIIs_ROMUpgrade_Jun2005.vm
Code:
English ROM
ROM: 1.40.00 WWE
Date: 03/10/05
Radio: 1.12.00
Protocol: 1337.42
ExtROM: 1.40.923 WWE
MMS: 2.0.0.21
BT: 1.0.0 Build 3900
I have tried several different media players, from windows media player 10, sompy media, and a few others, with no change.
I have tried several different stereo headphone/earbud combinations, which have worked on other 2.5mm socketed devices, no luck.
I am dreading the possibility its a hardware issue, so asking around before i start looking for service centers.
Can anyone shed some light? or have a similar issue?
Thanks.
It's a problem.
Your device cann't output anything by earphone?
It can output only a single channel.
The right channel is fine. good volume/frequency etc.
Handsfree kits are fine, mic and earbud works no problem.
It's just when i connect a stereo headset to it, no left channel audio.
I've more or less resigned myself to buy an overly expensive pair of bluetooth headphones to get around this issue, but i wish i didn't have to.
Especially considering the mediocre bluetooth radio performance i have been reading so much about.
And what if it is a software issue of some sort that i haven't seen?
200 bucko's more down the drain.
sad panda.
if the stereo headset it came with dont do stereo
and hardreset dont have any effect
then i'd say it's an hardware issue
if the org headset works then i'd say it's the headsets you try and or the 2.5mm -> 3.5mm converters which are the issue
I have same problem, My XDA IIs has been upgraded to WM6 CE OS 5.2.1933 by Xplode. I lost my left audio also while right audio working fine at my XDA IIs Stereo Headset.
Is it the hardware problem or software problem?
I actually gave up trying to make it work.
I eventually went with a bluetooth stereo headset from sony as a work around.
Does the job.

[Q] WM6 Atom Exec thinks Bluetooth Headset is hands free

Has anyone else had issues with using a bluetooth headset (earpiece actually) where the Atom Exec automatically goes into Hands Free mode when you make a call and therefor uses the mic on the device rather than the mic on the headset - it also makes the volume so loud it distorts in through the headset ???
I'm currently using the new 20071110A2WWE ROM by chartreux but have tried several other WM6 ROMs and have the same problem, also tried several bluetooth headsets. Currently using a Jawbone...
Any ideas?
*** Fixed my issues with Atom Exec thinking Bluetooth Headset is hands free! ***
After much reading I finally stumbled across this thread: http://forum.xda-developers.com/show...=308752&page=9
Using the utility AD2pTweaker (registry tweak) and doing a reset of my device and reselecting the "Headset" service in the Bluetooth config my bluetooth headset works like a charm!

Problem with A2DP

Hi ppls... I just bought a Jabra BT320s, a bluetooth wireless stereo headset. I got it to work work with my laptop and PC but unfortunately... I'm getting mix results from my Hermes... I'm using PDACorner V27.
Initial test:
I cant even get the A2DP to work. Only bluetooth headset works...
After doing a hardreset 3 times:
On the 1st hardreset, the A2DP worked when I press answer button, but the sound was horrible.... worst than mono speakers. After playing the song for about 25secs, the connection will break. I tried using a few players (Windows Media Player, Pocket Music, Pocket Tunes) also the same problem.
I decided to do another hardreset and even reflash the rom... unfortunately... the same problem is still there...
Any ideas or solution for this? Or are they any ROMs that give good A2DP output.... Pls help.... TQ.
Ouch........ 45views and no advise or solution.... T________T
Flash a different ROM, there is a a2dp fix floating around in a cab form, try installing that and see if it fixes it.
Thanks for the reply. Anyway, problem solved after I updated the firmware on the Jabra headset. It seems to be a firmware problem rather than a ROM problem.
