Hi all,
Laurentius and I are looking at resolving the current issues with A2DP (Many fixes will be in our latest rom, however issues vary from headset to headset.
Some work fine, others are poor quality and some receive PDA lockups or long pauses between streams.
Please could those with A2DP issues, and the need for this protocol to work properly, post the following information.
The current Rom you are you using
The make and Model of your headset
A list of issues you are currently having with A2DP.
Please also try the following to resolve the issue.......
HKLM\Software\Microsoft\Bluetooth\A2DP\Settings\
Remove (Delete the following entries)
BitPool
MaxBitpool
and add the following
[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\AudioGateway]
"Capability"=dword:0000003C
[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\A2DP\Settings]
"SampleRate"=dword:0000BB80
"UseJointStereo"=dword:00000001
Please then remove (un-pair) your headset and Soft Reset
After SR please re-pair Headset and test A2DP again.
Please keep this thread clean and only post A2DP issues with the required information listed above.
Thanks,
Cheers,
Beast
Hi Beast,
Isn't:
"UseJointStereo"=dword:00000000
to get proper stereo sounnd?

KOR!
I have latest V1 rom from Lt.Cmdr.Ivan - BT headset is Philips SHB7102 (works great with my Wizard and SEk800i). I did exacetely what U have asked for (but i have left jointstereo=0) and nothing happend. It sounds like 2s of music folowed by 15s of silence, then again 2s of music and 15s of silence. I messed with bitpool walues and couldn't find any working set. I'm afraid that's something wrong with max BT speed and not with A2DP implementation. I had BT speed switch app when I used broadcom BT stack and A2DP works great. Unfotunatelly normal mono BT headset doesnt work at all with this BT stack so I'm back to original stack

I've found that with MS stack and my Jabra BT620s the best bitpool is 33... good quality and good range (no interruptions)... jointstereo must be 1 otherwise the sound uses too bandwidth...

I also have Ivan's V1 Rom and have an Itech Radio headset. I completed the changes that you suggested and found that A2DP works well it did before the changes too. I have noticed that the sound quality may be a little better and the pauses are slightly reduced.
The main problem I have found with A2DP with all AKU0.5 ROMS is the pairing of the headset. If you soft reset you phone while the headset is on, A2DP will be auto detected when the phone comes up. If you play music then the music starts and stops and the phone becomes unstable. The work around is to turn your headset off, soft reset the phone. When the phone comes up turn the headset on and activate A2dp by pressing the button on the phone. Music then plays fine.
The registry changes you suggested did not help the above problem. AKU0.5 ROMS all seem to have this A2DP autodetect error on reset at least with my headset. Very frustrating.

Sorry I meant to say " When the phone comes up turn the headset on and activate A2DP by pressing the button on the HEADSET."

Hi Maniware,
Can you please further shed light in detail on the jointstereo?
Why jointstereo to be 1 or 0?
Thanks in advance!
KOR!
It goes well with joint stereo. Seems that it needs much less bandwidth. I've heard that jointstero=1 means that there is mono sound in effect.
"UseJointStereo"=dword:00000001 << mono
"UseJointStereo"=dword:00000002 << joint stereo
"UseJointStereo"=dword:00000000 << stereo

qtek 9000 - Logitech Mobile Bluetooth Headset
I'm not quite sure if my problem is right here - because i still have the original (last build) WM5 ROM (130.96 GER, Radio 1.09.00, ExtROM 1.30.185 GER).
I encounter statics while using the Logitech bluetooth headset, which is a mono one, making phone calls impossible due to stressed phone partners ... Only the person on the other end of the line encounters interruptions, me, as calling, not.
This is the main issue for me to update the ROM, and I'm trying to find out if any of your nice new ROMs will be of help.
Anyway, I haven't tried yet I'm afraid to destroy my device ...
thanx
Anna
my feedback:
device:
itech r35
Problems:
sound muted after 2 seconds of music.
audio players used:
audio manager
windows media player
i tried your advices, but not worked for me....
Sometimes it works when i put 70 (binary) on both Maxbitpool and bitpool...but on next device activation or reboot it just stop working...
A2DP and wireless
Just to be clear, my results are when I do not have wlan activated.
I changed UseJointStereo=dword:00000000.
Quality is good and it is definitely stereo.
Still have the auto detect problem. Interesting though, if I walk out of range for a while with the headset on, when I come back into range the A2dp is autodetect and the music starts playing through the headset again, quality is good. If I soft reset with the headset on and A2DP is autodetected, the headset is unusable.
If you do any of this with wlan on the quality is very poor with starts and stops.
Also noticed that audio manager does a better job with bluetooth than gsplayer, I think audio manager may have better caching.
Freezing
I think there's a problem with the latest core os files (AKU 0.7.0)... i havent' tried the MS BT stack, but with the Widcomm, using the bluetooth for anything more than 1 min, completely freezes the phone.
It does when listening music, transferring files, etc... if BT is idle, nothing happens (except than freezing the device when the Comm Manager gets confused and enables BT instead of gsm radio).
So it seems related to the core files.
Switching on and off, transferring data thru BT is a critical task and subject to lockups.
For the record, i used to use the BT A2DP and file transfer without ANY problem whatsoever in my old and horribly-underpowered HTC Tornado (omap850 @195mhz) so IT MUST WORK!
im using your latest rom and Motorola HT820 does not have a problem with it... even in the earlier roms you cooked... even tried it in indra's xoj version and darkforce's rom..
just wanted to clear it out just so you can rule something out...

I have the same headset HT820 and audio sucks, long pauses etc etc.
Can you post your firmware Revision for me please, it should be printed on the inside of the headband.
Cheers,
Beast
Haha.. can you help my friend Beasty please

Plantronics Pulsar 260
Sound stops coming fter about 1 second of playback (used TCPM,
Audio Manager)
The same result after applying those reg mods....
Please try and install the stack found here: http://forum.xda-developers.com/showthread.php?t=291639
A2DP problems should go away, but then will come the freeze-after-1-min problems, like with my HP Stereo bluetooth headset
I've flash to your latest WM6 AKU 0.7 (WIFI Fix update 3) ROM just now. But sadly to say, the freezing thing still occurs after playing music with Audio Manager. It even freezes when watching videos using WMP. Usually around 1 minute it shall start freezing. FYI:
Bluetooth model: i-tech Clip

I had the Qtek 9000 with italian version WM5 and i flashed WM6 with no problems. if you dont wanna have any problems unzip the attached file and add in the folder the 3 files (ms_.nbf ; nk.nbf ; radio_.nbf) from your prefered WM6 ROM (I personally use the latest Laurentius & Beast ROM http://forum.xda-developers.com/showthread.php?t=325466) start into bootloader (Power+backlite+softreset) and ROMUpgradeUt.exe
VERY IMPORTANT: you have to charge your batery before any flashing
My touch pro seems to have real bluetooth issues with my JVC KD-NX5000 stereo system. My kaiser worked flawlessly with it but with the touch pro it wont pair at times and when it does it wont let me use any of the many functions that the stereo offers (voice dialing, downloaded phonebook, etc) I assume this is a problem with the ms bluetooth stack and was wondering how tough of a job it would be to switch to a broadcomm stack or if anyone has thought about making a custom rom with the broadcomm stack. Just curious if Im the only one with issues with wm 6.1 and bluetooth.
i have the same problem with my diamnd anbd jvc car audio
Slightly OT rant:-
I had the opposite problem with pioneer + broadcom...
Pioneer only looks for handsets which identify themselves as phone or smartphone, and my device identified itself as a pda.
I actually told pioneer about the problem, and rather than forwarding on to the developers, I got a stock reply:-
"This phone is not on our compatibility list" (so we don't care)
So I went and got an MS based phone (you can change it to smartphone with a regedit).
Never buying pioneer again...

Similiar issue with my opel carkit.
Tried to make the broadcom stack working, but got a memory error when opening its blue tooth manager.
After uninstalling, bluetooth didn't work at all anymore, needed to perform a hard reset.
Has anyone successfully installed the broadcom BT stack on the touchpro/raphael?
I found that my Touch Pro would pair and then drop out when connecting to my Kenwood DDX5032 car stereo bluetooth adaptor. I couldn't dial from the Kenwood kit, couldn't use A2DP (wouldn't even connect), and really couldn't use any Headset Profile functions at all.
I persisted with pairing and unpairing in different ways (you can initiate the pairing from the Kenwood itself rather than the phone), but nothing really worked.
Then trinode's post about changing a registry setting sent me down that track and now everything is working fine
I found the relevant setting from http://forum.xda-developers.com/showthread.php?t=290871, which is [HKLM\Software\Microsoft\Bluetooth\sys\COD], and then changed the HTC TP default value of '5898764' (decimal), to the value from my old Dopod838Pro, which was '5374228' (in decimal).
I didn't even need to repair the Kewood to the HTC TP - it just worked straight away, as if it said "Oh, sorry, did you want me to work? I thought you wanted me to be in 'stupid' mode! My bad - everything will work now."
So all good, and thanks to trinode for pointing me in the right direction.
Codenix.
After hard-resetting my Touch Pro to fix another separate issue, now this problem has come back and this time changing the COD value hasn't fixed it. It would appear my previous post may have attributed my success to the wrong thing
The search for the answer continues!
I found a firmware update for my Kenwood's bluetooth adaptor which fixed the problem. I don't know why it ever worked at all before this update, but there you go!
I'll create a separate thread to share this with others in case anyone else out there has a Kenwood bluetooth kit and a Touch Pro or a Diamond.
Thanks.
The thread I created re the Kenwood is at http://forum.xda-developers.com/showthread.php?p=2835805
@ Trinode
Pioneer sent my unit back, but never told me that my phone was not supported. Where did you flag the smartphone in the registry? Did it fix the BT connection/unti reboot issue? I had a AVIC F500BT (sold it) now have a AVIC X910BT same issue as the 500 had.
@ Trinode. I found the hack , tried it, but it still doesn't resolve my issue. Are there any other mods out there for the BT Stack prob?
Hello --
Anyone aware of MOD and/or app that would allow user to tweak Bluetooth connectivity settings for ONE_S/Ville?
my ONE_S disassociates with car Bluetooth every 30 seconds, then reconnects, all day long. My previous FOUR Android HTC phones never experienced this problem. It's annoying as all hell
the problem drove me root my ONE_S with sole purpose of trying new TMOUS RADIO. This did not solve the problem.
currently, ONE_S running LeeDroid v2.1 with latest TMOUS radio.
same Bluetooth problem with car audio before and after root. Plantronics Voyager Pro headset at home works fine.
any suggestions would be appreciated.
Note: I have contacted dealer service to see if software update available for auto stero.
Check out a2dp volume in the market. It might help...
To the OP, there are other threads on this. Unpair your device from the Car, on the H1S go to advanced Bluetooth settings and turn off MAP, now repair and reconnect to the car ... fixed?
v looked in the advanced settings and can't see the MAP option. What is it exactly?

Second on A2DP volume... fixed my Bluetooth issues with the One S.
Anyone have issue with Bluetooth keep disconnect??!!!!?I tried two different Bluetooth already
Had some issues aswell, but then with the caller ID not sohowing on my car radio.
When developer options is enabled your can set a different Bluetooth AVRCP Version. Try to tweak with this setting, it worked for me.
