Problem with Windows Mobile and Bluetooth Headset Playing Audio

Hello guys,
I just got a Sony bluetooth headset and I am trying to use it with my HTC TYTN II. At first I paired the phone and the headset and I was able to listen to music and talk through the headset, all perfect. When I was listening to music, the bluetooth icon on my phone represented a music note and a headset over it.
When I turn the headset off once and then on again, it connects automatically with the phone but in some other mode. The bluetooth icon now represents the bluetooth sign with a headset over it. Now when I listen to some music, it comes from the speaker of the phone, not from the bluetooth headset. Talking through it is not a problem.
If I pair the phone and the headset again, it works just fine (showing again the music note) but once I turn the headset off and on again, I lose the music mode.
Does anyone know how to fix that? Thanks in advance.

I fixed the issue by installing AutoA2DP (found in this forum).

I've had a similar problem on my Tilt. I originally posted the following on the ROM thread. Since then, I have found that the AutoA2DP has not fixed the problem. I still have this issue about 70% of the time, and sometimes I can't get the bluetooth to work at all, not even after a soft reset. Sometimes it seems as if the bluetooth has no power, the phone can't communicate with the headset except when within a few inches of one another. Then it magically seems to resolve itself. Anyway here's my original post from the ROM thread.
The other day I installed an app on my phone called Schaps Network Plugin, which allows you to map network drives to the phone the same way you can do with a desktop. It allows me to access the home network directly via my wifi. It was something I needed and it seemed to work great, for a day. The next day my bluetooth headset would not connect. Long story only slightly shorter, it seems the problem was with the headset connecting via A2DP and doing so automatically. This always worked just fine in the past. Suddenly it wouldn't work. I tried a ton of things including a "fresh" install of everything and formatting my memory card to start with nothing on it. I flashed the original rom and then flashed this rom. I did hard resets each time. Did this twice. Even tried the bluetooth in the oem rom to see if I still got the problem. I did, and it is still with me. I can manually get the headset to connect via A2DP using the bluetooth settings, though even then it may take reconnecting several times to get it to work. However, when I turn the headset off and then on again, the A2DP does not reconnect, just the hands free. But the sound is not routed through the phone's speaker either, at that point. In fact you often get no sound at all, nothing via the headset or the speaker. OTOH, if you activate Voice Command, the headset does work while Voice command is running. After it shuts off, you are back to no sound. It seems as if the hands free works fine, but the audio gets partly routed to A2DP but does not connect to the headset. If I reset the phone, the headset connects correctly and efverything works until I turn the headset off again. Also if I pair the headset again, everything works correctly until I turn the headset off. Though pairing is not as trouble free as it used to be either. Sometimes it will not pair up wihtout repeated attempts. I did find this program, AutoA2DP which has patched the problem. It detects when a paired bluetooth device connects, and forces a connection via A2DP as well. But I never had this issue in the past, and my wife's phone still has no problem. I am not sure the Schaps Network plugin had anything to do with it, other than the timing. Seems odd to me that the bluetooth stack would suddenly develop issues that persist even after two fresh flashes of the rom. Any ideas, suggesitons, etc.? This is really bugging me, and although the patch seems to be working, the phone is still not acting "right." In the past, and on my wife's phone, if a bluetooth headset is turned on, it automatically connects, and all sounds, including the system sounds, are routed through the headset. Now, sometimes they are, and sometimes they aren't.

[Q] Bluetooth not working on Galaxy Nexus

Bluetooth appears to be broken on my Galaxy Nexus I can discover other bluetooth devices fine, and they can discover the Nexus, and pairing appears to be successful from either direction. But as soon as I try to connect/transfer a file immediately I get a notification on the Nexus saying 'connection unsuccessful', 'transfer cancelled by user' (when I didn't cancel anything!) etc.
I've tried this with three different devices (my old HTC Desire, my wife's HTC Legend and my MacBook Pro) with the same results on all three.
Has anyone else run into similar problems, or does this sound like I've got a faulty unit and should send it back? Is there anything I can do to troubleshoot this any further? (I've not rooted the phone and its running the stock Android 4 ROM).

I wish I had an answer; just got my Galaxy Nexus yesterday; it won't pair with any of my bluetooth(s) -- they were all working fine in my Droid so I know how to pair. Any suggestions? Help!! Thanks

After further investigation, it seems it's just outgoing connections that don't work on mine. I can transfer files from other devices to the GN fine, just can't transfer from the GN to any other devices. Haven't tried connecting to a headset or anything like that as I don't have one.
I asked an acquaintance who also owns a GN to test it out on theirs and they experienced exactly the same thing - everything works ok except for outgoing connections/transfers.
I'm wondering if its a software bug if that's the case. If it were hardware related you'd have thought the whole bluetooth thing would be broken.

FWIW: I have been able to pair and connect via bluetooth with my car, with no problem. Downloaded my phonebook to my car via bluetooth as well.

Bt phonebook pairing
I'm having BT issues as well with my G-Nex on Verizon. Will connect/pair with my car, works for making/receiving phone call audio, but will not synch the contact list. Thus, cannot use voice dial in my car (Nissan).
Have searched all over the internet, no real answers. Tried to disable the existing bluetooth PBAPservice as suggested somewhere else - no dice, and it just restarts itself anyway. I've seen some suggestion about rooting the phone and replacing the PBAPservice which may be my next step. Hate to root a phone this new when I may end up returning it if I can't make this work ... sorta a deal breaker for me.
Anyone have any suggestions? Could my phone just be defective? Seems like there are a number of BT issues around, but I can't find anything "official" acknowledging the issue(s) ..
Thanks ...

I'm having a problem with my new GNex bluetooth as well. I'm using a Blackberry Stereo Gateway (an A2DP adapter) in my car and it -does- work, but only after I toggle bluetooth off and back on again. That's kinda annoying.
Previously I had been using an Incredible and it was working fine.

Having problems with Bluetooth as well. I have a BlueFusion unit installed in my car. Worked perfectly fine with my Droid X. Every time I got in the car, it just connected and calls and music both played over the stereo fine. Got my Galaxy Nexus paired and it worked great. However, whenever I get back in the car and the Galaxy Nexus reconnects, the audio does not work. It says it's connected, it plays with no audio coming out of the phone or the car speakers though. Tried re-pairing, no go. Tried bluetooth on/off, no go. The only way to get it to work, is to reboot the phone every time I get in the car.

Does A2DP work properly? And what sort of bluetooth device are you pairing with?

Same here, sending files works, receiving doesn't. Pairing with my bt headset also works fine....

I had this problem when I fist boot the Nexus and after the first boot of the update to 4.0.1. Reboot the phone, re-pairing the devices and everything is fine since then.

I can't even get my Nexus to pair with my car (Kufatec FISCON unit for Volkswagen). Just straight up error "unable to pair" when I try it. :/

And I have a problem as well. I did get it to pair with my PC but I can't send any files from my PC to Nexus (it works fine with Desire).

I have two Nexus (one is my wife's) and both car have Blackberry Bluetooth Gateways in them. In both cases I am seeing the same issue as the OP, the bluetooth will not connect automatically. However if I manually power on the bluetooth on the phone when the gateway is in connecting mode than they will connect. I never had a problem like this with previous phones.
Is there a official way to inform Samsung of this issue?

I'm also having problems with bluetooth on my Galaxy Nexus. I wanted to transfer files via bluetooth from my old Incredible 2 to my new Galaxy Nexus and it just wouldn't work.
Edit: A reboot appears to have fixed the problem.

I have this same issue exactly - and had this issue after a System Update on my Droid Incredible for a few weeks before I ended up buying the Galaxy Nexus. I had hoped the new phone wouldn't have this issue. Anyways, it also seems to happen when I take a phone call.
Scenario: I'm listening to music over bluetooth to my bluetooth audio enabled headunit in my car. I receive a phone call, and toggle the bluetooth off so I can take the call privately over my phone's earpiece. When the call is finished, I toggle the bluetooth back on and the phone will connect - however the music is playing, but no audio comes through the phone nor the speakers of my car.
I started having this -exact- scenario issue when System Updates started rolling out for Droid Incredible, and they added the options for "Phone Audio" and "Media Audio" under the bluetooth options. Before these System Updates, my Droid Incredible had worked perfectly with bluetooth audio in my car.

I am having similar problems with both my car's BT phone and BT audio.The phone through my car gets terrible static until I stop and start Bluetooth again, which is dangerous on the highway.
I hope it can be fixed with a little software update.

I have the same problem with new nexus galaxy, pairs well with car bluetooth audio, can hear a confirmation beep on car speakers but no luck in the phone. It just stays on paired but not connected. It doesnt allow to remove pairing and redo it untill rebooting the device.

I'm also having issues with the bluetooth audio in my car. I pair okay with my Sony Xplod head unit, then when I turn off the car and reconnect, the GN starts playing music through the internal speaker instead of the car speakers.

I'm having the previously mentioned A2DP issue as well. Everything connects fine but occasionally, no audio is heard via the deck in my car. Phone calls via bluetooth work, just no A2DP audio.
For those having this same problem, you can fix issue by toggling airplane mode on and off. This is quicker than rebooting (which also fixes the issue).
This has to be a bug. I'm running 4.01. Anyone having the same issue with 4.02/4.03?

Yes. I just got mine last night...ran some errands today. Paired fine in my car, can make and receive calls through the car's audio system, but no sound. I'm running 4.02. Tried this with my BT headphones and the same thing happens.
The airplane mode trick works, however. Thanks!
Hopefully this will get fixed rather quickly!

Severe Bluetooth issues

Hey guys,
I'm having some pretty bad bluetooth issues, and my searches haven't really found a solution. When I attempt to connect my phone to my car headunit, my headunit shows it's connected and my phone also shows connected. But the audio still comes out of the phone speaker. After a few minutes it will disconnect and reconnect a few times, sometimes only showing headset connected and not media. Eventually the bluetooth just locks up saying "connecting...". If I turn off bluetooth on my phone, the stereo still shows it is connected to a bluetooth device. I tried to "forget" my device and re-paired, and the process seems fine except the phone never asks if I want to share my phonebook, so I assume something behind the scenes is already broken at that point.
This is a very new problem for me, and my bluetooth was working fine with this headunit for months now using numerous different ROMs from GB to JB. I was on AOKP JB build 1 when this started. I tried a full wipe and reflashed the ROM and still had the problem. I have tested this on about five other ICS and JB ROMs and am currently on CM9.1 and the problem is continuing. I also tried a different phone to make sure the problem wasn't my headunit and the other phone worked as expected.
Has anyone else had this problem, or does anyone have any direction for me to fix this? Thanks!

I have a similar problem with aokp jb, when it wasn't present before. The head unit shows my phone audio connects but the media audio does not connect sometimes. I would have to reboot my phone or fully disconnect my phone from the head unit and pair them again.. no real solution but it is slight work around and to say that you're not alone

Thanks. I've had to reboot or re-pair in the past every once in awhile, but neither rebooting or re-pairing is fixing the connection anymore. Anyone else had this problem? Are know if there is some sort of log I can find on my phone that might give some clues to why this is happening?

Problem Solved....
I tried my phone in a different vehicle, with a different headunit. No problems at all. I went through my head unit menus and found an option to clear all bluetooth data. I assume this clears all paired device information from the headunit. Everything works perfect now. Phone pairs fast, stays connected, and all functions are perfect. I hope this helps someone at some point.

Bluetooth connections problems.

Has anyone encountered issues with connecting with a car bluetooth? My wife phone conntects with no issues.. She can use the cars remotes to make and receive calls.. Mine I have to pick a contact from the phone for it to work, it will not work with the car or my work truck controls.. It seems everytime it ask if my car or truck can access my contacts, I always choose allow, but nothing happens, but it works with the wifes.. This is with the Lollipop update, that we both have...

happened to me I just rebooted my phone and it connected, also check settings for that paired device

Got one to work, in my truck.. The car it worked for a while, then quit.. I will try it agian to see if it will stcik... Most likely caused by the 5.0 update..

I've noticed a Bluetooth problem that suddenly started in the last week or so. I upgraded to Lollipop when it first hit, and didn't have any problems.
Now, however, after Bluetooth works fine for awhile (I can connect to a Pebble watch, Bluetooth speaker, car Bluetooth, etc) all day long - then all of a sudden it can't connect to ANYTHING. Toggling Bluetooth off\on doesn't fix it.
Restart the phone, then everything works just fine for awhile. Until it doesn't, and I have to restart again.
Anyone else experiencing this pattern?

I've actually had the opposite happen. I have a iSimple bluetooth box in my car. I've never been able to auto connect with either VZW Note2 or 4. The CS rep told me it had to do only with VZW phones and he couldn't help me out. On another forum, another member mentioned he didn't have any issues with his older phone, so I dug out my old HTC Incredible. Sure enough, it would auto connect. Something changed with Lollipop, and now my Note4 will finally auto connect to the iSimple box. I tried using a third party Bluetooth app prior, but it didn't fix the problem.

Finally got the one in the car working as well... Because the wife and I have the same phone, I just simply changed the name of my phone and it works fine..

If your talking about the developer edition one rom update.. YES.. What fixed mine was wiping everything and redoing the one rom lollipop, then twrp, then installing Ricks Rom Lollipop, things have been perfect. I even addressed it in the ricks rom thread the week.

I haven't had any issues connecting devices but since Lollipop, when I am connected to a bluetooth speaker (car, bose, other bluetooth speakers) the audio gets choppy randomly.
I have done some searching and found others (LG g3) who had the exact same issue after updating to Lollipop.
I have tried rebooting, using different music apps, unpairing/pairing, forgetting the device ect and nothing seems to work. Anyone else having this problem after updating to lollipop? Anyone know how to fix it?

Headset mic stopped working/barley working. Software issue.

Hello everyone,
My LG G3 is giving me a hard time, when I connect a headset, its microphone isn't working or it does but it's barley audible compared to the device's own mic.
The headphones part is working as usual and when the headset is connected sounds goes only through them like it should.
I've started using this headset a few days ago and it worked like a charm but then it's suddenly stopped working like it had been.
Fortunately I have another LG G3 on hand, so first I checked the headset with it and it works perfect.
So then I've replaced the 3.5 audio jack from the other G3 into my own to figure out if it is causing the problem and it is NOT,
since I got no improvement in my own phone and I also put MY jack in the other G3 and it worked there flawlessly with two different headsets.
I've been trying to record into / monitor with two different apps (lg audio recorder and another another one).
I've killed all apps running in the background. I've restarted numerous times, ran CCleaner to clear cache memories and whatever.
At one point a few days ago, maybe it was just before it started (and this might be a clue) the "plugged device" icon or "headset" icon on the notification bar stayed even after I've disconnected the headset and I think I needed to restart the phone but if i'm not wrong the headset kept working after that.
I was trying to find any kind of audio service to restart or anything like that but I didn't find any, I just killed them all to see if it helps.
I've also tried using "soundabout" app to try to force the audio path to the headset and played with some settings but to no avail (I disabled soundabout service after that attempt).
Right now I see no other option but a hard reset and I'm pretty sure it will solve the issue. but I hate going through backing up and restoring everything. and even so, who said this issue won't happen again? I've tried to search for an answer but found nothing like my problem on the web.
I just read something old from 2013 that mentions a bug in android audio. not sure it's related. something about "AudioPolicyMangerBase" (it seems I can't post links yet) from an app that had a switch to switch between headset mode or phone mode. but in any case it's no longer maintained. again, not sure it's related.
Update: Now I got no sound with two different headsets on the SECOND LG G3 as well. it seems messing with it around, plugging and unplugging messes with it's software somehow and maybe it locks the audio route in a way that it's can't work.
Any way to reset all audio ins/outs routes in the device?
I'll appreciate your help. Thanks a lot!
Roy.
