$100 if you fix it: Loss of speaker audio after BT connections

Hi all, I have had this bug in varying flavours with both the Wizard and now the Kaiser.
If I make a call via Bluetooth (certain devices only e.g. JVC in car stereo), after the call, all audio is lost on the device when using the speaker, e.g. no ringtones, no TomTom voice guidance. (Oddly the touchtone sounds on the phone dialler continue to work.)
Making another call via Bluetooth works fine and all audio is heard, but not if calling via the earpiece of the phone - all phone audio is still muted. A reboot is required. (Even after a reboot, sometimes all audio is muted, and 2 or 3 reboots are required.)
It is like Bluetooth is 'stealing' the audio from the phone's speaker (which is should), but not giving it back at the end, however turning off Bluetooth doesn't return it.
It happens with WM6.x on the TyTN II.
If you can fix it either via a workaround (reboot the audio service after every call?) or a direct fix (HTC are useless and have not emailed me back), I will pledge you $100 via PayPal. I am sure others will join me in pledging an amount also.

Yes. I've seen the same thing with the last stock Tilt ROM, too.

Same here. But is not happening very often.
The other issue for me is if I have A2DP enable and listening to music, then making a phone call will drop the A2DP connection and I have to reconnect A2DP again. It happens to both my JVC car unit and Sony HBH DS220.
I tried that w/ Dutty's WM6.0 and the latest 6.1 rom

I have the same issue, with bluetooth disconnects.

Just staying on-topic here (you can solve A2DP issues with A2DPToggle a great free app), has anyone found a solution to this Bluetooth loss of speaker audio issue, or a workaround to avoid it happening?
Rebooting the phone after every Bluetooth phone call is hardly what I consider a high-end smartphone to require.

Same here
What Radio's are you guys running? (Ignore my signature for the moment, been phoneless and away from here for a while and just getting back up to date )
Haz

My current radio is 1.64.08.21.
I have also tried 1.64.06.04.
Could we be closer to finding the problem? Does the Radio contain the Bluetooth stack?
Here are all available Radios:
http://wiki.xda-developers.com/index.php?pagename=Kaiser_Radio
I'm going to try 1.58.26.20 now. I suggest others try the other 1.5x variants and report back if any of them solve the bug.

Update: I am now offering $100 to anyone who can fix this - see 1st thread.
I have used Windows Mobile since the first ever SPV phone. This one issue is making me look seriously at abandoning that loyalty and getting a Blackberry. If I can fix this for $100 I could be tempted to stay however.

Have you tried BT Audio Toggle ? (found at http://pdaphonehome.com/forums/sams...luetooth-headset.html?perpage=20&pagenumber=1)
Maybe if this helps with your problem then a mortscript could be written to automatically run the utility after a phone call.

What bluetooth headset do you have? Have you tried other headsets or just the one you have? What version of 6.1 are you using?

Thanks, I'll give the audio toggle a go. Might need some help with Mortscript though
I am using the JVC KD-BT1 car stereo with Bluetooth in-car kit. However I can also lose audio on a clean boot even when not in the car, although that is very rare. When using it with the car stereo, it happens after almost every call.
I am running Sleuth's WM6.1 but the other people in this thread are using a variety of BT devices, ROMs, and HTC models.

Can anyone help with how to create a MortScript to run BTAudioOff.exe after each phone call?

Flash a NIKI radio. I had a similar issue with my JVC in-dash CD player and I just got all the radios and tried them all. All the NIKI radios seem to work a lot of the time, while some work and others don't.

Okay I tried this and before I even got in the car, chose to turn Bluetooth Audio off using the toggle. Since then I cannot recreate the issue! I am not having to toggle after every call, I only did it once and the problem won't come back!
Fingers crossed...

NP. 1 more thing. What do you mean all audio is lost? Do you mean that the auido goes through the bt device? Or just that there is no audio coming from either at all. If that's the case, then all you might have to do is go to Comm Manager>Settings>Bluetooth>JVC (or whatever you named it) and uncheck the Stereo sound and viola it should work unless you are not using A2DP >.> . I think it's either directing all sound to your bt device or trying to send sound to it but failing.

The issue is there is no audio coming from either the phone or the Bluetooth device. I hear the Bluetooth device disconnect, and its display shows that it has also.
I see no 'Stereo' option to untick for the JVC in its Bluetooth settings, only Hands-free and Wireless Stereo (already unticked).

No progress
Okay, this is seriously getting me down now It all sounded so promising. I have tried the following:
Flashed Niki Radio 1.58.21.23
Tried using Bluetooth Toggle - it seemed to work once when I turned BT off before connecting, but after a reboot the problem is back
Tried a HFP extension PM'd to me (thanks anyway - didn't help)
Made sure Bluetooth Stereo is unticked in the JVC's settings on the phone
I am not sure if the problem is worse when taking a call as TomTom is running.
Here is an interesting development which might help someone narrow down the cause:
I make a few calls, and as always audio is lost, even for phone calls sometimes.
Touchtones on the keypad are the only sound that the phone continues to emit itself. Everything else (TomTom, ringtones, etc.) is dead.
I then go into the JVC's A2DP mode and 'Connect'. The icon appears on the mobile's title bar, and I can hear phone audio through the car stereo.
I 'Disconnect' and the phone's audio is still lost.
What this tells us is that the phone is putting out sound, just not through the speaker.
If someone can write something that will reset the speaker driver after a call, my offer for $100 still stands.

Just to update this, the issue still exists with a clean install of HTC's new 2-May-08 WM6.1 ROM from their website. To***rs!

CJSnet,
Since we got the similar setup w/ exact the same issue (Att Tilt w/ JVC BT-1), I think the problem is basically Kaiser does not switch back to A2DP profile properly after headset profile from phone call. The same issue happens to my Sony HBH DS-220 stereo headset too.
I tried my Eten M600 w/ JVC BT-1 and does not see this problem

A2DP Bluetooth Audio interrupts

Hi Guys,
i have this problem for a long time and didn't find anything about it in web or in xda forums.
I have a HTC Dream + HBH-IS 800 Sony Ericsson Headset.
When i listen to music via A2DP the connection is not very stable...
the connection interrupts very often for about 2 or 3 seconds, then works for about 3 seconds.
This only happens when i am outside, not in buildings. I this the reason is because of interferences. The connection gets better when i move the G1 into a specific orientation (upper side up) and don't turn my head to the right
On my old Windows mobile phone i played around with bitpool (=ratio between quality and connection stability by constant bitrate) settings... is there a possibility to get the connection more stable, when playing around with this setting?!
How can this setting be changed on android?
Further information:
-ROM Cyanogen 4.2.5 but same problem on stock ROM
-HTC Dream has been replaced one by a new device -> same problem
-Headset was never exchanged, but worked perfectly on my old Touch Pro with WM 6.1
Thanks for your help

There is a known issue on the Bluetooth stack and is suppose to be fixed in the Elclair 2.0 fix, the temporary work around is to first pair and connect then disconnect and reconnect it again i'm having to do that several times a day when i use my RocketFish bluetooth stereo headset. Hope that helps

thanks for this workaround, will try it tomorrow and will post if it works for me too

hmm, didnt really work for me... no change after pairing disconnecting and connecting again.
i wonder why this only happens outside, not in buildings... another frequencys which interferences maybe?!

Be sure to disable wifi.

Not trying to hi-jack your thread. If you want me to open another i will. However this is a BT question as well.
my G1 is set to connect to my stereo in my car. Pioneer BT head unit. I find that i have to manually tell it to connect every time i get in the car. When i had a blackberry before it would just connect every time on its own without me doing anything once i made the initial connection.
Any ideas?
thanks.

Worked on Dell Streak A1.6

I have Dell BH200 headset as well, and I have the same exact problem its like the audio stutters but when I first connect it its more stutter than music so you can barely even understand the music until after 30secs when it starts to normal out.
ATM im runnning Stock 1.6 for G1, im going to try Cyanogenmod 6.0 tomorrow and see if anything changes.
but everyday I go back and forth with my laptop and phone since my headphones run for atleast 3-4 days.

wow, finally someone having the same problem.
and even the same description of the connection issues.
I recently bought a orange SanFran and, as the device is fairly cheap, a nokia bh-504 along with it.
The connection isnt stable even when I put it in my breast pocket.
As soon as I move my head to the right, the streaming stops. Completely.
I can easily stop the music when holding my hand in front of the right earpiece.
so i will try the disconnect / connect again "workaround", but I don't think that will help.
I paired the same headset with my gf's netbook and I could walk through the whole apartment and the signal was stable even through up to 4 walls.
so no one here knows how to tweak BT settings in android?

Bluetooth Connectivity Issues

I got my Nexus 7 last week and have not been able to put it down. Recently I got a bluetooth keyboard to go along with it and it brought some major bluetooth connectivity issues to my attention. Has anyone else had any issues with bluetooth accessories on the Nexus 7?
The problems I have been dealing with:
When connecting to a bluetooth device whatever screen I am on on my tablet refreshes (ie: home screen redrawn, chrome all tabs refresh)
Bluetooth connectivity drops momentarily (tethering or connected to bluetooth keyboard)
I'm trying to figure out if it's the unshielded speakers on my office desk or if it is an actual problem with the bluetooth module on my Nexus 7.

Quick update, I've been able to recreate the issue with the screen refreshing/redrawing when a paired device is connected and disconnected. It seems that anytime you connect or disconnect a bluetooth device it refreshes whatever screen you are on (if it's a browser window where you've filled in a bunch of text on a forum you will lose all of it because the browser tabs refresh as well).

While I have not tested this specific BT setup I can confirm that the BT performance on this device is horrible. Specifically with BT headsets when used with any VoIP app or even Google talk.
I hope it is just a software issue and will be fixed with an update.

Here's a quick video of what's going on with mine. I have another Nexus 7 arriving today so I can test to see if it's just an issue with the one I currently have.

I have been unable to play an .avi movie with a bluetooth headset, it freezes after a few seconds. It plays no problem without it. I have also had issues with the tablet becoming very slow when tethering to bluetooth, at least for number of seconds (> 30), presumably when it got internet and started syncing...but no slowdown on the wifi, so it wasn't the syncing with the issue, but the bluetooth part of the communication, I believe. Anyone else been able to play movies with a bluetooth headset or speakers?

I have had no trouble at all with Bluetooth. My Samsung Hs3000 works great with music,movies and any internet or sys sounds. It Also has a very good range of at least 75ft or more in the open and covers my downstairs when inside.

I have been able to pair 2 headsets. 1st had no function at all, ext. mic did not work and no sound- using groove ip or playing music. 2nd was a stereo bluetooth set with ext. mic. No transmission with groove ip. However, with this one I was able to listen to music.
Also paired with 2 phones. One with JB-( Gnex )and one (Note)with ICS. No data transmission to tablet with either one over bluetooth.

same issue - getting sound on voice
I've bluetooth paired with phone and media audio connected.
I get the sound but not mic.
This is with nexus 7 4.1.1 using novero rockaway headset...it works fine with the ipad.
any ideas? I'm stuck.

[FIX] Possilbe A2DP Streaming Workaround

Stuttering and skipping streaming are very known issues on many jelly bean devices.
The most times when I listen to music in my car, i do this via bluetooth. So it is really annoying me and some day, I will have an accident, while I am fumbling with my HTC One.
I replaced the audio.a2dp.default.so with one of the Nexus 4 (4.2.2) and it just worked well, but only the first time using bluetooth streaming after rebooting the device.
I changed some settings in audio.conf and it still stutters.
But then, i deactived wifi while the device was streaming and all stuttering and skipping was gone.
So... can someone just confirm, whether the a2dp streaming works correctly, when wifi is deactived?
I want to know, whether this is the only point to get this work and I don't want to change my working mess

is nobody interested in this?

I posted this bluetooth issue a while back on this forum, and the issue is corrected by switching off WIFI while using BT. Apparently the new update which is due soon fixes the issue but only one user has confirmed that so far.
Since I use bluetooth streaming on the car mainly, I use Tasker so that when Bluetooth connects, it automatically switches WIFI off (don't need WIFI while driving and saves battery), and when it disconnects it switches it back on. This way the phone just works seamlessly.

Just turning the wifi off and back on again when I connect bluetooth seems to solve this issue for me.

i can confirm - turning wifi on/off fixes it as well for me (until next time I go bluetooth)

I discovered this a couple of weeks ago too. I was about to send it back too. Cant live without podcasts and audible in the car!

I have the problem that i cant even here any sound on my HTC CAR A100 Car Stereo Clip, even if wlan is deactivated With my old sensation everything is okey..

I wonder if this also improves the bitpool value. I'm noticing on my HTC One that bluetooth streaming quality is not very good. From what I've read it has to do with a bitpool value that it set too low, increasing this value is supposed to increase the streaming quality. Highs sound distorted on my phone over BT I can't believe Google/HTC have not addressed this issue.

I have not been able to solve the bluetooth audio streaming issue by turning off WiFi for my car. It works perfectly fine with my Jambox even with WiFi turned on, but in the car, it does not work either way and I'm using software version 1.29.401.13

I'm running 1.29.401.13 too and it looks like it is working nearly perfect for now. I can remember only one time, when it stopped for a second. Mabye the car radio is facing similar problems? Did you try to update the firmware or whatever of you car radio?

Did you manage to fix the problem with the A100 as mine is exactly the same, works fine on my Sensation but no the HTC One.

have the same problem:
If wifi is ON and bluetooth is ON, eg at streaming youtube over the bluetooth headset, it stutters and has distortions.
If wifi is OFF and stream a video from the sdcard over bluetooth all is fine.
what i find out:
I use the JellyBean from Quarkx for defy.
The build from 7.3.2013 worked
All later builds, with the new wifi driver had this problem.
But its a known bug that JellyBean has a2dp issues, i guess.
This trick, to change audio.a2dp doesnt helped me

I didn't noticed any problem with my phone even when the wifi ON, I'm using the latest radio "4A.16.3250.24_10.38.1150.03L" found in this post: http://forum.xda-developers.com/showthread.php?t=2245615

Google Home Mini + BT speaker = stuttering music

I encountered stutter when broadcasting music from GHM to my BT speaker. It's like buffering every second. With the Internet connection everything is ok. The router is located near the GHM. When connecting via BT to the phone or through AUX with any other source, my Marshall Acton plays music without any problems. The problem occurs only when the music is broadcast from the GH Mini. It started a couple of days ago. Up to this point, there were no problems for a week. It happens randomly, it can play an hour without stammering, and then start, or vice versa. The GHM itself plays without problems. Tried TuneIn and Google Music. I also tried to reset GHM.

CC Audio has no Bluetooth

Has anyone encountered this problem?

The same thing has been happening for me as well. It only occurs when playing to a Bluetooth speaker. Playback via the Google Home Mini speaker itself is fine and it is right next to the wifi router.
What firmware are you on? Mine are on 1.32.118652. I think it's a preview firmware so it may be a bug in the firmware as nothing I do has made it any better and it was working fine before and has only started over the last few weeks.

I bought the Home Mini yesterday and found the same problem. Any update about it?

Same
Same here. Stuttering music. Thought I was the only one and there was something wrong with my BT speaker. Stuttering music. FW 1.32.118652
Managed to get it working by unpairing and forgetting, and re-pairing. Now it happens every time my BT speaker goes into sleep mode.
More irritating is that when this happens the Google Home Mini defaults back to its own speaker instead of trying to reconnect.
This is firmware basics. Let's hope they iron this out.

My BT speaker will start to studder with about 25% battery left now or when it's actually plugged in. Fresh charge will run fine.

I'm having this issue too. I'm at the latest update at the time and using Harman Kardon Aura speaker

I'm having the same issue on GHM in 2022, using an Anker Soundcore Flare 2. Seems like Google has not fixed this issue. Does anyone know if Google Nest Mini has the same issue too?
