How to use A2DP in Galaxy Nexus?

I just bought a bluetooth headset (plantronics M50, bluetooth v3.0 with A2DP), the phone call is OK, but when I play video, music, the speaker of phone is on, the headset not work, need additional setup? need addtional apps? how?

You shouldn't need any additional apps. When your phone connects it should connect with two "profiles", one for the phone and one for the audio (A2DP).
In the manual for your headset, does it tell you that you need to switch to a certain mode to hear a2dp audio?

solved, just reboot the phone, and you can chose phone audio or media audio in bluetooth setting interface.

I need bluetooth help please

(NOTE - I WOULD START A NEW TOPIC, BUT CANNOT AS I DONT HAVE ENOUGH COMMENTS TO DO SO).......
Just got a new car (Mercedes Benz GL450), and trying to pair my GN to the bluetooth functionality of the car. First off - the car doesnt even support Bluetooth audio, which was a major disappointment, but it has an ipod dock (yes, it is a 2012 $80,000 truck that doesnt have a usb, or basic features that a freeking $15,000 hyundai). Either way, I can connect my GN to the bluetooth phone feature no problem, it pairs, and automatically connects with no issues. I bought a coolstream A2DP bluetooth receiver (http://www.amazon.com/CoolStream-Bluetooth-Receiver-Speakers-docking/dp/B008EL58YA) to plug into the ipod dock. The GN sees it, i try to pair, enter the password, and it wont connect to it. I have read forums all over the internet about how the GN Bluetooth has many issues - does anyone have a solution??
I read here (http://code.google.com/p/android/issues/detail?id=24012) that i should toggle airplane mode, switch bluetooth on/off, reboot phone, and bluetooth receiver, etc.... it all doesnt work. Tried A2DP Volume - not the issue, it just wont pair after i enter the password.
I am currently rooted on 4.1.1 XenonHD ROM with Franco Kernal, have tried it with 4.1.1 Vicious Jellybean/Faux Kernal as well - no luck.
Going to try it with 4.1.1 AXI0M ROM, and see what happens..................
Has anyone else run into this issue on any other ROM, that can suggest a fix - note - I am good with flashing roms, kernals, mods, etc....but if you ask me to code, i am clueless.
Thanks to anyone that can help

2008 GL450, only old **s 30 pin Sh*t
Tried many sorts to work with steaming...no go so far.
Pre-historic technology was specially installed on GL's....so to leech out more from customers..MB sucks.
Please let me know if you figured something out mean while.

[Q] Bluetooth A2DP issue with Car Stereo

Ok, so here's the deal. I have a rooted T-mo G3 (D851) on a stock rom, out of the box it's been awesome to use with my Pioneer AVH-X2600BT head unit in my scooby. I was messing around with themes a short while ago and then the bluetooth stopped working intermittently. From what I can tell the mix-rate of the A2DP stream changes from 44k to 3hz and all you hear are beeps at multiple amplitudes. The beeps are playing out of the buffer in the head unit until it empties then it resets the connection to the phone. It still plays out these beeps until it's empty even if I disconnect the phone from the head unit.
I don't have this problem with two other iPhones. And previous to my screwing around, it'd work flawlessly since a bought it (launch day.)
Could I have screwed up a mixrate setting someplace? I do have a custom mixer xml for boosting headphone port and speaker audio but I never touched the settings for the bluetooth driver.
This behavior is intermittent and it matters very little what content I'm playing through it. I do notice that when this is happening, no metadata or control is capable through AVRCP either. (i.e. Pandora app can't connect to the phone, no album art, etc)
Sometimes it'll stop doing it and play normally for the rest of the session (drive) after a few minutes and everything is normal. Sometimes it doesn't do it at all and sometimes I can't get it work normally at all.
Here's a video showing the behavior:

Reset your Bluetooth on your headunit and pair it again with all your bluetooth devices.
I had a similar problem with my LG G3 and my Pioneer AVH-8500 where my Pioneer will not recognize my LG G3 anymore but recognizes my Note 3.
I fixed the problem by resetting my Bluetooth on my Pioneer and had to pair all my devices back to it again.
You will have to look into your Pioneer manual on how to reset your bluetooth.
Edit: I just remembered something.
Did you happen to update or change your firmware.
Some KitKat firmwares are missing the Bluetooth Metadata and will not function properly.

Use autoaudio download it from playstore. This fixes my problem on metadata

Hey thanks guys.
I reflashed the bt radio in my head unit and the problem so far has seemed to go away. Metadata and everything works again.
I appreciate the heads up from another pioneer user.

How exactly did you reflash the bt radio? I have the same head unit and am having problems with it dropping the bt connection to my G3

I just got forced to upgrade my LG G3 to Android 5.0 and it completely screwed up my Bluetooth audio connection in my car.
Bluetooth sync to home audio playback is fine, but BTooth audio is completely corrupted with the Pioneer AVH-X2600BT.
I cant find the instructions on how to reflash my stereo firmware to reset bluetooth settings. I cleared my bluetooth devices in the stereo setup, but to no avail. Can you point me to instructions on a reflash?

I am having the same issue. I have 2 other bluetooth devices that my G3 will connect to and playback is fine for as long as I have battery life. But when connected to my Pioneer AVH-x2600bt, I get constant skipping after 2 minutes of playback. I can pause it for a couple of minutes and when I start playing again it's fine for another 2 minutes. I have done a hard reset on the Pioneer and reconnected my G3 but no change. I have unpaired and cleared all of the bluetooth data in my phone and reconnected, no change. All of the Kit Kat OS devices I have still work fine with the Pioneer but none of the Lollipop devices work. I emailed Pioneer, their reply was for me to take my deck to a service center. That will do no good. One of two things needs to happen, Google needs to update their bluetooth firmware or Pioneer needs to update the firmware for the AVH-x2600bt. Until one of those two things happen I guess I'll be using stone age technology, an auxiliary cable.
Thank you, that is all.

Hello
I can't sent the music to my car radio according to the version of Android. In version 5.0 with different kernel that doesn't work, and with 5.1.1 (blisspop) it works. I 'm preferred the custom rom because I like some features. Someone have a solution or an explanation of why?

Bluetooth display of songinfo @ car problem

My car (Seat Leon 5F with Media System Plus) suddenly displays no more song info and the progressbar is f***ed. I hoped Oreo would change it, but it doesn't.
However other phones combined with my car work and my phone works in other cars. I already tried resetting the Media System. It seems it has something to do with the AVRCP version.
Any ideas?

I have got the same problem (no song info on my car's media display) after upgrading to Oreo (it was fine on Nougat).
Modifying Bluetooth codec/AVCR version in developer options didn't help.

did a full wipe and installed 5.0.3 from scratch, it's working now

A full wipe also restored music meta-data, however music controls (track skip/repeat) from the steering wheel do not work. Worked fine on Nougat.

I don't want to do a full wipe.
I tried unpairing and pairing with my car again - didn't help (still no song info).
Does anyone know what files should I delete to reset Bluetooth settings without a full wipe (I'm rooted, so can access/delete any file)?

They don't work for Bluetooth headphones and they don't even work for wired headphones FYI

I have found a solution that works for me:
1. Set Google Play Music as the default music player in the settings.
2. Reboot.
3. Problem solved.
Weird stuff...

Bluetooth connection car

I tried everything but there's no connection to my car system only s Media Player my Galaxy watch has been detected I did a reset changed and erased everything etc.
Normally my car detects every smartphone but the watch is still a problem maybe there is a workaround
Thank you for all your help

Question Audio not routing to Bluetooth earbuds

Anyone having issues with audio not routing to Bluetooth earbuds? Only fix for me so far is to reboot the phone. But the issues comes back later or the next day.
It's strange too, I'll have issue with the galaxy buds pro not working for audio or phone calls but I switch to the Sony XM4 and it works for audio but not for calls. Reboot and both works again. I've tried unpairing and resetting Bluetooth and also the earbuds but nothing works except reboot of phone.

Network reset and try clearing the system cache.

Try swiping down once then hit media output and selecting the Bluetooth device there

not sure if these will help as well but these were the solutions i have done when i had bt issues. these are not in order by the way, but alternative solutions
1) clear the bt cache. unpair then pair again
2) i installed bluetooth audio widget
3) i once bought a jam loud buds from jb hi fi. it would drop out or it wouldn't connect at all to my fold. turns out it was still paired to my old samsung note 9. had to delete that pairing and it finally worked with the fold. didn't know some devices only paired with a phone once
4) bt version. i had an old bt remote used by my daughter. it paired with the fold but did not work. did some reading and the bt version of the remote could be the cause
5) above posts from blackhawk and sonin66

Buds+ software and firmware* have given me a lot of trouble. A real pain. I'm running two N10+ N975U/N975U1's one on Pie the latter on 10.
These are the apps I load but they may not work on 11 or higher, don't know... In any case uninstalling then reinstalling may fix your issue if the network reset fails too. Firewall block "Apps (UID)10343" and Wearables Installation Manager. Keep them blocked or they will update... and you'll be repeating the process.
For all these apps they must have all their permissions enabled to open!!!
*if you have a pair of Buds+ do not upgrade their firmware! It trashed the sound in my one pair. Now they need reflashed...

done this, and the correct device was selected but no audio. Sometimes music audio works fine but not calls

Idk if this happens for you guys but I went to a sony showroom today and when I paired my mobiles with some soundbar units like sony HT-S40R, HT-G700 and HT-S500F and some other models soundbar all of them got this weird issue, we can hear the music but every 2 or 3 sec it feels like it stops and then resume ( on the music player app it's working normally) I though maybe because of my spotify app I tried Youtube, youtube music amd amp all of them gives the same weird results ... This was before rooting my phone ... Ofc after rooting it it's stil the same issue (Android 12 and 13) hopefully this happened with those specefics models and not with my earphones or headphones bluetooth
Also note my S21 ultra works perfectly with the models said above
