Bluetooth AVRCP 1.3 - Cannot hear media

so... I think I've narrowed down my issues with newer ROMs coming out and my bluetooth not working in the car anymore. just a little background information,
- 2011 Toyota Camry SE w/ JBL Audio
- Verizon Galaxy Nexus using various ROMs
prior to any newer releases, I would use voice/audio over bluetooth, ran great without a problem. I didn't get metadata on screen but was ok. pandora, spotify, notification sounds, google music, etc... worked like a charm.
well... now I noticed that only voice calls & google music work over bluetooth connection in the car. I thought this was first an issue with pairing the device to the car, so I deleted all the profiles in the car and redid connection on phone. I still couldn't get sound out of any other media application i.e.; pandora, youtube, notifcations, spotify, etc... I could only get google music to work correctly. the apps not working look like they are playing, I turn off bluetooth on phone and it continues playing, but when bluetooth is on I hear nothing.
so after researching, I see that majority of new releases include AVRCP 1.3 which pushes metadata to the displays. I noticed this now works with google music, but I can't for the life of me figure out how to get other media services working properly. I've researched on RW, Google, other Android forums and can see some have similar issues, but the thread soon dies. [/background]
can anyone tell me if I can use an updated ROM with AVRCP 1.0 instead of AVRCP 1.3 to test? does anyone have suggestions I could try to get other media services working? thanks!

I think it's AVRCP 1.3 in CM 10 based roms that breaks this. I just switched to jelly belly 9 (4.1.2) which rolled back bluetooth profiles back to AVRCP 1.0 and pandora etc. works but without media info obviously. I also saw a AVRCP 1.3 patch for Pandora somewhere that may make it work. It's possible that the problem isn't that the ROM is not compatible, but that the Apps aren't.

Ok... I've confirmed it has to be AVRCP 1.3
Last night I took advice. I installed Jelly Belly 9 "4.1.2" w/ reverted AVRCP 1.0 because of BT issues, and this morning I went to work, tested connection with BT and everything worked! So... Looks like the issue lies with AVRCP 1.3. I don't see metadata on screen anymore but it doesn't bother me, I'd rather have all other media players working.
To touch on what others are saying, statements Google Music works perfectly fine with AVRCP 1.3 based ROM's as well as voice through BT. It's just the other media players i.e; pandora, slacker, youtube, notifications, etc.... that don't work. I'm guessing from what I read, is that the applications do not support AVRCP 1.3 and will not push to Toyota head units properly. Not sure if this is going to get fixed or not, but sucks because this limits what I can/can't use for ROMs at least a solution was found and reason why. Thanks bud!

You could also try https://github.com/loganakamatsu/PandoraAVRCP for the Pandora patch. Maybe patches exist for other apps as well...

I read on another thread that any app that supports the Scrobble Droid API hxxp://code.google.com/p/scrobbledroid/wiki/DeveloperAPI will pass the meta info to AVRCP. So I assume if you install ScrobbleDroid app hxxps://play.google.com/store/apps/details?id=net.jjc1138.android.scrobbler&hl=en from the play store any app that it is compatible with will also pass the meta info to the display.
As noted, Pandora is not supported as it does not broadcast its intents. I personally had issues getting the PandoraAVRCP github to patch. If anyone has a patched pandora.apk, I would certainly appreciate a PM.
Good luck.

[Q] bluetooth metadata

I don't think this is a Note II question directly, but the Note II is what I have experience with, so I'll ask here.
I went to Best Buy to try out bluetooth pairing my phone with the car stereos. Aside from the pain of trying to get some of them connected, in the end I was able to see song metadata using the stock music player, but not spotify. I searched the web and it appears spotify doesn't have AVRCP 1.3 (yet?) which is supposedly the reason for this.
Then I decided to make a more prepared trip: besides the former two apps, I additionally loaded Pandora, Slacker Radio, Last.FM, MOG, and iHeartRadio. I went back to Best Buy and found while for the most part I could get any of them to play/stop/fwd/rev, none of them showed the metadata. One exception is I was able to get one ($500) stereo to do Pandora (including album art), although then I could never get it out of Pandora mode (I didn't spend too long at that, I was tired of testing by that point).
So my questions are:
1. There seem to be three versions of AVRCP: 1.0, 1.3, 1.4 but I can't find which the Note II has. I'm guessing it's at least 1.3 because the stock player was able to pass metadata. Anyone know?
2. Is it really true that basically every app is missing support for passing metadata? Or is this related to the specific Note II ROM or the stereo firmware?

If you use Spotify or Pandora, there are modified apps that support metadata.
http://forum.xda-developers.com/showthread.php?t=2081475 is one for spotify.

Pandora on car radio not working.

Has anyone successfully gotten pandora to stream to another device. My car radio doesn't seem to work with Pandora anymore.

I came from an Iphone 4 and have Kenwood DNX99x0 installed in two cars. I tried using Pandora with my kid's ICS phone and it worked perfectly so I assumed it would work with Note 2. NOT.
Apparently, Note 2 has a newer version of Bluetooth version 4 which the Kenwood cannot handle. Contacted Kenwood tech support and no help. They will not support it as the force you to upgrade to their newer models - Kenwood sucks in this respect. They are busy fighting with Crapple's new connector too.
If you use the "bluetooth" audio setting on the radio, Pandora will work but you will not see any album art, not be able to change you stations, but will be able to pause and play from the radio.
What I ended up doing to get the radio Panador interface working is connecting my old Iphone 4, refreshed with new IOS connected to the old Kenwood Iphone cable with WIFI turned on in airplane mode. I have the wonderful new ROM that let's me wifi teather so the the old Iphone goes through the Note 2 to connect to internet and Pandora works perfectly. I am sure you could do similar with any older phone.

Im using Kenwood KDC-X996 / KDC-BT952HD And Bluetooth works fine. Pandora does not work on the Note2 But it does work on the Note1, S3. It has something to do with JB. And the Pandora on these headunits allow trackskip and thumbs up and down.

Note 4, Pandora, Lollipop, or Toyota Problem?

just got a new Note 4 running lollipop, connect to my 2015 tundra via bluetooth, run pandora, and get no track info or album art/etc on the dash screen... tracks play just fine, but would really like this feature back... old S3 works just fine to show track info still... pandora version is the same, so idk if this is a pandora, lollipop, or a toyota problem.

I'd say it's a Toyota problem with not working correctly with Lollipop. As long as everything worked while on KK, then it's both car and Lollipop.

My note 4 on 5.0.1 does not work with our RAV4. It will connect for a short time and then disconnect. Very annoying

No streaming metadata while using Bluetooth streaming.

When on oxygen is can see the song that's playing on Spotify on my radio of my ford fiesta mk7 2011.
But when I flash all of the roms Bluetooth streaming works great but the radio don't show the song title.
What can be the cause of this, i tested with various settings but nothing really helps.
Someone got ideas where to look to fix this problem? Or how to fix this?

I assume you're already in Oreo? This is a well known Oreo issue.
I suffered this on my Nexus6p when I upgraded to 8.0 and 8.1.
When I switched to OP5T, the same thing happened after the 8.0 update.
I heard that this metadata issue does not occur on Google Play music. But like you, I prefer Spotify.

Hi, are you still having BT metadata issues?
Try this:
Go to Developer Options, and look for Bluetooth AVRCP Version.
On Android 8.1, this should be set to 1.4, but you should see an option for 1.3. Set it to 1.3.

Hi! Just came across this thread here on the forum. I currently have a Volvo V40(2017) and it worked flawlessly with my iPhone 6S through Bluetooth. Every app I used to stream managed to get the metadata there, that being Spotify, Apple Music or even Twitch!
I ditched the iPhone and bought a OnePlus 5T and now when I do pair the device with the car and stream music through Bluetooth this happens to me. The only thing shown on the car monitor is Audio Streaming without any additional information about it. I already tried every single Bluetooth AVRCP version available (1.4[Default], 1.3, 1.5, 1.6) and not one works. Also I'm currently using Apple Music but I don't think it matters because other applications also don't pass the metadata as well.
It's really annoying not being able to see what is currently playing and its also the only thing about my recent iOS to Android change I'm sad about so far
Any other ideas on how I can solve this?
Thanks!

I feel your pain.
Back in 2014, I had a nexus phone that was running on Kitkat. And in addition to the song metadata, etc., I am also able to use my car's voice dialing function to make calls on my phone. But when Lollipop came out, my car's voice dialing suddenly stopped working. But at least I could still make calls and I still had metadata.
When marshmallow came out, my car's dialer suddenly stopped showing the profile picture of the person I'm calling (or calling me). The clock sync function also stopped working. But at least I can still make calls, and I still had my audio-track metadata..
Up until Nougat 7.0, the audio metadata still worked.
It was when Nougat 7.1 came out that I lost the metadata.
When Oreo came out, it was a hit-or-miss affair. Sometimes I get metadata. Sometimes I don't. I could not figure the correct sequence that I followed to get the metadata to work.
I was lucky enough to find the AVRCP tip from a Honda Car forum.
I'm sorry I don't have any other ideas at this point.

i have Pixel 3xl with Android 10, - Bluetooth connects fine there is no metadata - song info. this problem started with 8.1 Android version and I have not been able to get it to work. I really cant believe google cant fix this issue or even aware of it. plenty of threads on google. I think they all use Iphone, i am guessing ...this is very annoying. I have change the avrcp version from 1.4 to 1.6. no luck, also I read that turn off battery optimization on Bluetooth. no luck. any suggestions would be appreciated
