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

[CJSnet]

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.

[jackleung]

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.

[CJSnet]

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. :eek:

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 :) )

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:

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.

[CJSnet]

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/samsung-i730-i830-i830w/54951-utility-redirect-all-audio-bluetooth-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.

[SH4YD33]

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?

[CJSnet]

Thanks, I'll give the audio toggle a go. Might need some help with Mortscript though :rolleyes:

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.

[CJSnet]

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.

Thanks, I'll try that too.

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! :confused: I am not having to toggle after every call, I only did it once and the problem won't come back! :rolleyes::cool:

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).

[CJSnet]

Okay, this is seriously getting me down now :mad: 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 phoneI 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. :o

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! :mad:

[jackleung]

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

[SlyTuk]

I have these issues too - Very very annoying.

What use is a phone when you cannot make or recieve calls without having to do a soft reset everytime ?

[chaosxj349]

I am using a stock HTC Tytn II and also use BTAudio. This problem always happens now when using S2P v0.40 if I'm listening to music via my bluetooth headset and a call comes in, after I disconnect from the call I have to soft reset my phone to get the audio back again.

[CJSnet]

I for one have had enough of HTC's incompetence. I emailed them over a month ago about this thread and they haven't even bothered replying. They can kiss my future business goodbye, as can Microsoft for allowing such crap to go on.

I will be getting the new Blackberry Bold at the earliest opportunity and selling this piece of junk for 99p on eBay.

Shame they want to lose this lifelong customer this way as I've owned HTC since the very first SPV phone, but it's their choice. A phone that can't make phone calls - ha! :mad:

Even my A2DP/headset got disconnect, all I need to do is just re-connect instead of soft-reset

No, I mean I can make calls and hear the person on the other end just fine, its the music on the phone or the default sounds that are the problem. If someone calls me after that, the phone just vibrates, no custom ringtone. Normally I would at least hear a ping each time I move up or down the device volume slider, but not even that. Device audio just up and disappears, period. That used to happen with an earlier version of S2P as well, but I can't remember which one, but it happens consistently with this new version.

THought I'd point you guys to a mortscript I wrote (http://forum.xda-developers.com/showpost.php?p=2267998&postcount=516).

I use this script to automatically re-enable A2DP once a phone call ends. Maybe something similar could be put together to fix the problem you're experiencing.

[NuShrike]

This is happening with the latest L26v5 ROM too.
