Bluetooth Handsfree Connected, but no sound

Hi if someone can help me it would be much appreciated. I just bought a Touch Pro and everything is working fine....except for one really annoying issue.
Whenever I connect my bluetooth to a headset, it shows connected but no sound is coming out. The sound is muted. when connected to my Audi, I see that the phone has bars (shows connected and I can dial the phone), but when I make a call no sound. Similarly on my SE HBH-DS970 headset. The A2DP works perfectly, but when I make a call nothing.....I've searched google and through XDA and no solution.
Can someone suggest a solution? I've soft/hard reset the device already. If I should change Radio ROM which one would someone suggest that's stable? Thanks

If no one else has this problem, can anyone at least suggest to me if this sounds like a Hardware or software issue? If hardware I will return it, but if software I will try to find a solution. Like I said the phone connects to BT, but I just can't get handsfree to work. File transfers and A2DP work. Thanks

Just flashed to UK ROM and still no help....I've read some people having the same problems over at the Diamond thread...I'm the only one answering my own thread here hahaha....if anyone can help I'd greatly appreciate it. Thanks.

Hi,
I occasionally had such an issue with my Parrot CK3100, but I did not get the time yet to investigate further. After the call was connected I did not hear anything, and I am not sure whether the other party could hear me.
On another day, the handsfree was working perfectly OK.
Cheers
Michael

Thanks for replying Michael....I'm at a loss and I tried all the suggestions posted. I hope it's a software issue...I'm going to buy a bluetooth headset tomorrow and see if that works. It's not the end of the world, but annoying since all my ppc, s60, BB, and UIQ phones prior to the TP have not had any such issues.
Do you think it's a software issue?

have you tried playing music?

Yes.....A2DP works perfectly....no problems whatsoever with file transfers either....I'm guessing either it's a software problem or the phone has a new bluetooth software that's not agreeing with my older SE headset, but the car is another issue. The Car is 2007 and I'm sure the Bluetooth software is not that old. I've tried Euro WWE and Asian WWE ROM and no go.....I'm going to try the Cingular ROM and see what happens.

Just another quick update....I tried 2 other different bluetooth headsets and still the same problem... for some reason the sound for handsfree will not come through...anyone know of registry hack possibly that will allow sound to come through?

May not be entirely related to your problem...
Mine is worst...whenever I have paired my Jabra or iTech BT headset, when the phone rings, 8/10 times the phone will auto pickup (and no I did not setup the phone to auto pickup) and the it will NOT connect to the bluetooth. Instead it will be just like an auto pickup and the sound will come thru the phone headset. This is driving me nuts!!!!

[Q] Bluetooth Issues

Does anyone have problems connecting their Desire S to Bluetooth devices?
My phone seems to pair to my Bluetooth hands free kit but no connection actually happens. The same situation for another Bluetooth kit i have and also my laptop!
I just upgraded from a normal Desire and it worked perfectly with all the devices.
I tried changing the radio and also upgraded the Rom from 1.28.401.1_Radio_20.28b.30.080 5U_38.03.02.11
to
1.47.401.4_Radio_20.28I.30.085 AU_3805.06.02.03
I have searched for solutions but have not found any on XDA

Might be that your bluetooth device is in a black list need to check, can yo utell what bluetooth device you have exactly?

My main Bluetooth device is a Merlin Car Mirror Kit V2.
When connected and properly paired it should 'beep' twice, but now it just connects and the phone says its paired. When you make a call it shows it is dialling but no sound comes through both ways.

[Q] Sensation XE: Bluetooth headphone problem.

I am hoping somebody would help solve my problem. I have a Calypso SP bluetooth headphone. My phone shows it's connected to the device but the sound from music player still come out from the main speaker.When i got the sound to the headphone, there's this crackling sound coming out. I have tried pairing and unpairing the device a few times, but the results are still the same. It doesn't have any problem when paired with my galaxy s.

same problem here i would also like to know if there is a fix.

What ROM are you using?

IGNORE - misread your question, sorry. Many people experience poor A2DP audio quality on the Sensation. Some headsets seem to sound okay, others don't, even though they may be fine when used with other devices. Search and you'll find some info in various threads. More recent ROMs have solved or reduced the problem for some people.
Just a quick check, are you paired to your device for both phone and media audio?
To check, if you're using Gingerbread, go into Bluetooth Settings (settings/wireless and networks), then press and hold on the device you are connected to and select 'options' in the menu that pops up. This will take you to another menu where you can check which features you are connected to. Sometimes mine only connects to 'phone audio' on my headset and I have to re-enable media audio.

Thanks for the reply. My phone is on stock firmware. This problem only happened recently. Before this i never encounter this problem. I found another problem where the volume control doesn't work when I'm using bluetooth. The same problem also occurs when i use the original earphone where the volume control detects bluetooth device even when it's not paired. I tried resetting my phone earlier and the problem is still there. Maybe i'll take it to the service center and have it fixed.

Fixed, with some sacrifice..
After fiddling around the whole night, i tried to do the restore factory setting from the recovery mode. Somehow it fixed the problem. So it might be some software or an app bug that caused the problem. Now to do a some serious apps downloading and setup.

Bluetooth issue in car

Whenever I connect my phone by Bluetooth to my car's stereo, only the front speakers work, nothing from the 2 rear speakers. I've tried adjusting the fade and checking settings in poweramp but still nothing. I'm not sure if this would be an issue with my phone, the ROM, or the car audio system. I'm thinking it's an issue with the car's audio but I figured I'd ask here in case somebody else has had the same issue. I am on liquid smooth 3.0 April 24th build with elemental x kernel but I had the same issue with my galaxy s4

I have no problem with nexus 5 and my car Bluetooth connectivity.
Make sure that your audio system, GPS and make and model are compatible with the bluetooth from the phone. Some other connectivity issues are that the car kit cannot decode the Bluetooth device that it is trying to connect. This decode means that the system cannot recognize the name. This is a frequent problem when devices have been upgraded. While your system may have worked fine before, upgrades can cause problems because the compatibility all of a sudden changes. This is an issue that has not really been addressed by the manufacturers.
Another frequent problem that can occur is that the Bluetooth will connect but then it will not stay connected and only one speaker is running,. Many times this can be a hardware issue.
So the bluetooth device can connect but it does not work properly. In this case there is an issue with the stereo connection to the Bluetooth unit. There is nothing actually wrong with the bluetooth or devices but this is a software issue. To fix it see if the manufacturer is offering any updates. If one person has had the issue then you can bet that many people will have the problem. This is a problem with the car kit software as no matter which phone or earpiece you use the audio will not play from the speakers. Check that the vehicle supports bluetooth audio as some only will support bluetooth phone calls. These are 2 very different things.
Most of the time, look into the settings for the bluetooth and the car system. If the car battery should die then the system may reset to the defaults. This means that all of the current settings will be lost and need to be reset. Not only will you need to check the settings in the car system but also in your phone or other bluetooth device. In order to correct the bluetooth settings the device will need to be connected to the computer.

I have an aftermarket Kenwood double DIN deck with Bluetooth 2.1. It connects perfectly fine, shows up with Nexus 5 when pairing, shows the song title, shows the name of the person calling... It works great when plugged in through the aux port, but of course doesn't show me any information that way. When I had the S4 it showed up as SGH-M919. It stays connected just fine and I had it playing for a while before I tried turning up the volume and noticed it didn't sound right and figured out the rear speakers weren't playing.
I just checked and noticed there is a somewhat recent update on Kenwood's site but it was still about 3 weeks before I bought the deck... I'll try doing that though. (edit) just checked again and the update isn't for my model, there's no software for it
Thank you for answering since I'm pretty sure now that it's a problem with the stereo and nothing to do with Android lol
Kind of embarrassed to admit it but...I did have Car Toys install it so... they probably didn't do a very great job. I knew I should have had either Best Buy do it or tracked down a friend that could do it. Oh well

[Q] bluetooth pairing issue, how to solve?

Hello, so i bougth this great phone, but bluetooth pairing(+autoconnect) is not working at all.
So to the proplem. My opo IS paired with my alpine car stereo, but everytime i go to my car opo asks IF i want to pair it...and obviously it should just connect automatically since i have paired it earlier but no.
Is this some known issue with opo or my device just making me headtache?
IF anyone have had same proplems i would love to hear how you managed to fix it.
PS. All my old phones automatically connected to car stereo after pairing once, so its most definatly opo issue and not the alpine stereo.

Okey, i got this solved by doing 2 things, but because im stupid and didnt test it between these actions i cqnt say which one did the job or was both needed.
1. I cleared "paired devices memory" from my alpine stereo.
2. I cleared paired device list from my handset(opo)
Hope this will help someone else in future who got proplems with alpine receiver and opo.

Problem solved! bluetooth pairing and buffering issues
Hey problem solved
I had bluetooth pairing and buffering problems and now everything works perfectly. what I did was flash OPO_OxygenOS_1_0-modem-flashable.zip (you can find it somewhere in google docs..don't remember the link)
anyway after doing that everything works perfectly.
I am running cyanogen 12.1 nightly build from 20150601
then I flashed the modem.

Technical solution...too much ?

Hello All,
I too was facing issue with the Bluetooth connectivity. My headphone "Jabra Halo Smart" worked perfectly fine with other android devices but my OnePlus One. Issue i faced was that my at times my headphone would get detected but the headphone controls wont work. It was really irritating as i could not use the functionality of my headphones.
What i did was went into the Bluetooth options. Clicked on the setting icon beside my headphone and unchecked and rechecked the options.
Another action i performed was un-pairing the Bluetooth headphones from my device and resetting my headphones paired setting.
Third option was resetting the Jabra app that i installed on my mobile.
Fourth action is restarting your OnePlus device.
The above actions i performed in different orders. So one of them should surely help.
Suggestion provided by OnePlus Call Center: (which i did not need to try )
--> switch off the device
--> Press power+vol down button simultaneously
--> Select English language
--> wipe cache partition
--> wipe cache
--> reboot device
Advice while using Bluetooth headphones or speakers (especially Bluetooth devices having the functionality to connect multiple devices)...switch off the Bluetooth device and then switch off the Bluetooth of the host device (mobile, laptop, etc) and then connect the Bluetooth device to the other host device
Do not keep two host devices Bluetooth on...at times it causes to store the connection setting in the cache causing the Bluetooth device to act strangely. :cyclops: :cyclops: :cyclops:
