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
AFAIK
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...

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
Hello!
I bought a HD2 a last week. I noticed 2 problems during playing audio:
1. Music stops in standby mode after last track ends.
2. I used my own 3.5 mm headphone (not headset, so it has no built in microphone) and when I got a call nobody could hear me. Can I use this time the device built in microphone somehow?
Please help me solve this problems!
Thanks in advance!
(sorry for my English)

no one knows ?
When I use my earphones i talk through the phone's mic, and with your song problem try the repeat button
I had same problem. I now use s2u2 to lock phone. works great with hd 2.
you can set it not to lock system, and this then allows music to continue when the device locks.
from what he said sounds like u got a problem because i had the shipped rom and when i played music i locked the device so nothing would happen to it while i was listing to my mp3 but i also use the htc head set ...now on that note i tryed using the hd2 head set on the hd and u can not use the play fuctions on the headset, so htc made it sum how that allows u to only use the head set in any mode, anyone wants to run with this
Hello,
I am currently using MegaJet V2 ROM.
I have problem with the phone audio of my bluetooth device. I am using Jabra Pebble. It is working fine with other non rooted phones but when I use it with my rooted phone; media audio is fine but while making or receiving a call; hissing sound (noise) is the only thing that I can hear. I had the same problem with my previous ROM (Legoice Turbov3.1) thats why I changed the ROM but problem still persists.
Can anybody please guide me regarding how to fix this problem...??

Hello guys, anyone use a bluetooth headset? if yes, what brand is it? i use LG tone+ that support bluetooth 4.1, a2dp and apt-x, but the problem is the sound frequently become distorted, especially when my kenzo far enough from bluetooth headset (50 cm +). Is the problem with headset or rom i used? i use miui 8 dev cn. thanks for help.
hey, i think its headset related. im using a AudioMX Bluetooth Over-Ear headset and it works within a reach of 4-5m. after that distance i have problem with audio distortion.
I have a sony SBH60 and it works flawlessly. No distortion at all, and little to no "audio lag" (I mean audio/video sync), at least I haven't noticed while watching classic youtube content, I don't use my phone for movies or TV Shows.
For me I am using Samsung level U and everything works well. Besides, I have a portable bluetooth speaker too (china brand) and also works.
what rom do you use guys? i use miui dev cn official. thanks.
I'm using latest xiaomi.eu rom
Sorry for the late reply, I'm using 8.1.3.0 Global, always kept my phone up to date, no issues so far.
Also tested with my in car Pioneer MH380, a Logitech MiniBoom (UE), and a MPOW Bluetooth transmitter.
I've never had any issue with bluetooth whatsoever, maybe a clean install could help.
Hi, anybody having their sounds lagging every 10-30 seconds? I'm streaming via bluetooth to my car head unit and the sound keeps disappearing about a second and it's pretty annoying. and only this phone having this trouble. Update/clean install doesn't help. I'm using global dev.
Hello guys ,
I'm a happy owner of this phone , i have a little problem with bluetooth connection with my car(a Renault megane MK3 2009) and my father's car (Renault Kadjar 2016)
sometimes it pairs correctly but when i play music or video the output sound comes only from the right speaker , when it happens i need to restart the phone and the sound work correctly .
Do you have any idea how to solve this problem ?
bluetooth codes is the problem
After some researches , i found that this problem is related to the bleutooth codecs , unfortunately i haven't found any solution for that.
