[Q] No Bluetooth Audio - Transmission or Reception - on Phone calls - Galaxy S II Q&A, Help & Troubleshooting

I have a Jawbone ICON bluetooth headset. I used it with my iPhone 3Gs with no problems. I got the Galaxy S2 last week and installed Villain Rom. I paired up the headset and it worked great. A couple of days later I tried it again and there is no audio at all. It doesn't send my voice and I don't hear what the other person is saying. I do hear the various beeps, etc to show a call is being made, but as soon as there is a connection - nada.
I CAN use the headset to listen to audio from a video so the headset is working correctly. The pairing is fine and I can actually use the button on the headset to set the volume of the call - but no sound.
I've tried:
1) updated firmware on Jawbone to latest, includes A2DP
2) Installed Jawbone app on my phone - can see battery indicator, etc, etc
3) unpair/deleted the connection and recreated it
4) Made sure that both phone and media are selected for the connection
5) Updated Villain Rom to 2.4.2
6) retried steps 2-4 with latest rom
I'm sure that I didn't pair my headset until after I installed Villain the first time. I'm also sure that I didn't mess with the phone after it worked - because I was away for the weekend. I probably did install a couple of apps, but nothing related to bluetooth or that required root.
Any suggestions as to what to try next? I'm assuming that the audio is muted (can it be muted both directions?).
This is really important because I have the low microphone volume too (and any suggestions on that front would be appreciated too).

Just an update... Its finally working.
I believe the final solution was a manual reset of the headset. I also disconnected/unpaired the headset, repaired it and went into the bluetooth properties and removed permission to share media audio. After these changes it started working. Subsequently I went back in and re-enabled the media audio and it still works.
You would think updating the firmware would reset the headset, but apparently not.

T959D - SlimICS - Bluetooth Volume Weirdness

I've flashed my T-959D (Telus) to SlimICS 4.2. Everything seems to work great (after I remapped the vol keys to reverse them back) except for bluetooth weirdness in my car.
The phone pairs correctly and I can make and take calls just as before, but at first glance it seems that while media audio was shown as connected, there was no sound when I played an mp3. So I tried a headphone cable into the aux jack of my car stereo and still nothing. However, when I pulled out the headphone jack from my phone, suddenly I had media playing over bluetooth... but only for about 2 seconds when the phone then mysteriously muted itself. I can repeat this process at will. No sound until I pull out the headphone jack... and then only for a second or two, then the phone mutes.
I'm assuming this must be some sort of setting or mixup with regards to the headset removal action. But I'm not sure where to check on this. Is there some sort of setting for it that might be screwed up? I really rely on my bluetooth audio for podcasts and music playback. I might have to go back to PassionICS since it worked there. But so far I like SlimICS a whole lot better and would rather get this working if I can.
Update - after installing the HeadphoneStatus app from the market, it appears that the phone thinks the headphones are plugged in when they are not. Not sure that this is a hardware issue since the thing worked perfectly this morning before flashing the rom.

[Q] Liquid Smooth 2.7 jfltevzw handsfree issues

Hey, just flashed Liquid 2.7 for my S4 and everything seems to work great, except for hands-free calls through the included S4 headphones. I go to make a phone call with my headphones plugged in and no joy. I've also tried pulling them in while on an existing call and they don't work either.
Has anyone else experienced issues with making hands-free calls with Liquid 2.7 jflevzw? Just shooting in the dark, maybe installing Xposed might help?
Quick update, when making a call via my BT headset while my headphones are plugged in (or plugging them in during call) I have all my sources available to me: BT Headset, Wired Headset, Phone, Phone Speaker. When I change to the wired headset, no call audio comes through, but phone interaction noises route through the headphones.
I've tried to fix permissions through TWRP, but no change . That's about the only troubleshooting I've done.
Also, if you're thinking of flashing to Liquid, know GPS is a little funky. You need to turn off Wifi & mobile network location (Settings/personal/location) or GPS won't work.
Apparently this is an AOSP issue according to the guys over in the DEV forum.

[Q] S4 bluetooth connectivity failed/skewed - please help

I have a Verizon s4 running 4.3 (all ota updates, nothing custom), my bluetooth connectivity seems to have suddenly gone...awry. When I connect any bluetooth headset (I have tried with multiple) the phone will register it connecting to phone and media controls. I have it set to automatically start music playback when this occurs, and while this worked before, it spontaneously changed. Instead of playing through the headset, music now plays through the earpiece speaker and the volume buttons control phone audio rather than media (note, audio will still be transmitted out through a jack, but again the buttons will not control media volume). The headsets themselves are fully functional as they still control call functions and voice search, but no longer toggle audio, let alone control playback. This effect continues even after the headset disconnects until the phone is rebooted.
The only thing I can think of having caused this is that I recently downloaded the pebble companion app (I wanted to test it out to see what its like before I decided to buy the thing or not), and the issue started after that. I uninstalled the app and rebooted/removed battery, but still the same issue. Is there any way to fix this other than a full system reboot? I'd really rather avoid that if I can help it.
I appreciate any feedback on this issue, thanks in advance!
I have exactly the same problem, I thought I was crazy or did something stupid! I thought it had to do with my root modifications until I completely wiped it out with an odin restore and redid only the root and SuperSU and it still had the issue. I used to have it stream bluetooth audio to my car and for some reason it once I started playing music and I thought it was really quiet even for my phone speaker until I noticed it coming out of the earpiece as well. I've run out of ideas as far as fixing it at this point though I'm still trying things.

Bluetooth media sound?

Hey Guys,
Received my phone earlier last week and started to try out some bluetooth headsets with it to see how it worked,
First thing I noticed I was only able to make and receive calls, no media (youtube) or navigation sounds would play through my bluetooth device until I got an app called "BT Mono"
I Gather it being a new phone some things won't be perfect until further roms are developed or existing ones updated
I'm using a (Marque A170) By Plantronics headset,
I have checked the settings to ensure (Media Playback) Is selected.
I've tried this particular headset on an iPad and it works without any issues

Bluetooth car stereo connecting as "(no phone)"

Hello,
Need some help with phone calls not passing through Bluetooth to my car stereo.
It's a new stereo, the old one died, but I could make/receive calls with it without any problems.
The new stereo recognises BT media audio, but not phone calls (incoming or outgoing).
The BT settings screen shows the car stereo as "Connected (no phone)"
I am using [ROM][Slim][6.0.1][AOSP_r74][Slim 6 For Kenzo][21/11/2016] and I saw two posts here and here from @DoubleDroz experiencing the same issue.
I would ask at that thread, but unfortunately it has been locked by @Umang96.
I've seen this problem mentioned before with some ROMs.
I know the phone's BT works fine because it worked with the previous car stereo only yesterday (and it works with the new stereo for media audio).
I've tried a few apps from the PlayStore but nothing sorted the issue.
Ideally, I'd like to stick with this ROM, old as it might be, as I find it just fine for my needs (I don't play any games, it's work only).
But if I have to install a different ROM to get bluetooth calls in the car I will because it is a necessity.
I don't want to install MIUI though, can't stand it.
I would use Krexus-CAF if it hadn't the issues with GPS navigation, which is also a necessity.
Any ideas or suggestions?
Hi, i found fix for bluetooth "NO PHONE" on car set. It's work on latest LOS rom. Follow this post.
