Chromecast Audio Questions - LineageOS Questions & Answers

Hello,
I have a Motorola Moto G3 ('Osprey') and have installed Lineage OS on it (currently on 14.1-20170413-NIGHTLY-osprey). The new OS is great but I cast to a couple of Chromecast Audio devices fairly often and have noticed the following changes since installing Lineage;
- Previously it was possible to adjust the volume of the music playing from Google Play Music to a Chromecast Audio with the screen turned off by rocking the volume rocker on the 'phone. Now the screen has to be on (i.e. it's necessary to press the on/off button before the volume rocker.)
- Previously it was possible to 'take over' a Chromecast Audio session from another Android device; by opening up Google Play Music and casting to the devices that are running the playlist and the song that is playing would appear. Now this is not possible.
The 'phone was running the standard Android Lollipop before I installed Lineage. Is it possible to regain the functionality that I had before? I don't know whether it's relevant but I installed open_gapps-arm-7.1-stock-20170326 and the 'phone is rooted.
Thanks in advance for any help.

Bit more detail on item 2 above; if there is music playing from another 'phone on a Chromecast Audio then it possible to see what is happening from my 'phone, you can pause the music and mute it but can't do anything else. Previously it was possible to take over the session and control it in the same way as if you had initiated it.

AVRCP bluetooth not working?

Audio/Video Remote Control Profile (AVRCP) is not working on any app. i tried it with my headphones to play/pause and skip a song and nothing. same thing on my car. so its definitely the phone causing the problem. anyone else?
Same here - tried two different devices. No play / pause.
OK, it looks like Google Music has a strangle hold on AVRCP. It works in that app (which I don't use) and nowhere else.
This is one of the reasons I ditched Google Music on my last device. The minute you install it, no other app works with AVRCP.
I tried disabling it in Applications (I am running stock w/o unlock or root ATM), but that does no good. Also tried re-enabling and FC, but again, no joy.
Hopefully someone more skilled that I has a suggestion...
EDIT - there don't appear to be any settings in Google Music to turn off their control. Tried a couple apps in the market like Headset Interceptor, but they did not help.
no google music isnt the problem. it doesnt work on any app. plus on my old phone google music didnt cause any problems and worked just fine.

Hmm... I guess we have two different problems.
On my GNEX, AVRCP (I only care about playing and pausing via BT) works on Google Music, and nothing else.
On my old DINC, I had AVRCP working until I installed Google Music (only change I made), at which point all my other apps' AVRCP capabilities stopped working (Audible, Subsonic, etc.). I then uninstalled Google Music (again, the only change I made), and my AVRCP started working again.
To me, that experience makes it pretty clear that Google Music was causing me grief on my old device, and is mysteriously the only thing that works with this feature on my new device.
Like I said, maybe you have something else going on.
so noone else has this problem?
Try Power Amp
The Power Amp player seems to work on my Senheisser MM450 BT Headphones
I have the same issue.
AVRCP on my bluetooth headset (Plantronics BackBeat 903+) stopped working when I started using Galaxy Nexus.
On my old phone I was using BeyondPod and Player Pro with my headset and play/pause worked from the headset. Now, I cannot stop or play music in those apps.
I can confirm that this has something to do with Google Music.
I found that if I start Google Music then AVRCP works with the headset. If then I go and start Player Pro, the AVRCP stops working, and pushing play/pause button does nothing. Then, when I go back to Goolge Music, everything works fine once again.
So existence of Google Music somehow hampers the ability of other apps to claim bluetooth headset remote control fully. They claim it partially, because Google Music is not starting music on pushing play button, but the player does not start music as well.
Spotify on Nexus S stopped responding to BT Play/Pause after ICS update
I am encountering the same issue after updating my Nexus S to Ice Cream Sandwich via an OTA update.
Using Seinnheser MM450s, I was previously able to fully control Spotify (Play/Pause/Next/Previous). However since updating to ICS, only Next/Previous work. The main button (Play/Pause) has no effect.
However, when I launch the factory Music app, it responds to all controls.
To try and 'debug' the issue, I downloaded a trial of "Headset Droid" app, and used its BlueTooth command monitor debugging facility. As expected, it correctly intercepted and confirmed the Next/Previous button pushes, however failed to acknowledge the Play/Pause functionality.
Has a bug report been filed regarding this issue? Can anyone suggest a workaround?
Thanks - Anj
I have the same issue. Previously - my Nexus One running stock/unrooted 2.3.6 worked perfectly for play/pause/next/previous/start|end call on cheap Chinese Bluetooth headphones. Been using them for weeks with Subsonic, flawlessly.
Moved to Galaxy Nexus, 4.0.1 (apparently .2 hasn't rolled for my geography yet) - same headphones, only next/previous/start|end call work. Play/Pause does nothing in either state, whether I am in Subsonic or not. Haven't tried Music yet as I never use it (lets face it, its of limited value outside the US!).
But I did notice that if I press and hold for quite a while, the play/pause button, it seems to stop the music in some way that isn't quite pause, but nothing else works after that, you have to manually restart it from the app.
(anecdotally, I have the unsubstantiated feeling that some/all system sounds are not piped to the headphones as effectively as Gingerbread. But I haven't tested this yet)
Finally, I note I have occasionally used these headphones on my Honeycomb tablet - Asus Transformer, 3.2.1(?) and it behaves the same as the Nexus One, not the Galaxy Nexus so this is definitely an ICS issue.
I have reported this fault on code.google.com/p/android/issues/detail?id=23172 - please add to the comments so that it gathers momentum as an important issue.
I hate to post a me-too, but me too :-(
I'm using doggcatcher on a rooted verizon galaxy nexus on the stock 4.0.2 firmware. My headphones are a sony MW600. Play/pause/ffw/rew don't work in doggcatcher.
I started up google music and went through the setup wizard. the AVRCP buttons work for google music only. Enabling/disabling doggcatcher's "bind to headset forcefully" option has no effect.
I used Titanium Backup to make a backup of Google Music, and then uninstall it. Now Doggcatcher responds to AVRCP button-presses. Anyone else want to give it a try?
Thanks daoist,
Can you confirm that you have to be root to use that particular functionality of Titanium Backup?
Thanks again - Anj
Interesting. Now it seems like google music and Pandora both respond to it. But google listen does not.
Sent from my Galaxy Nexus using xda premium
I'm having the same issues with my Galaxy Nexus as well. I starred the link mentioned above. I'm using a Plantronics Voyager Pro HD and none of my music controls work. I also can't tap the call button to engage a voice search or anything. I hope Google fixes this sometime soon...This makes my headset quite a bit less useful...
I can confirm the issue on my Gnex LTE running 4.0.2. Google Music works fine. I don't know why, but Doggcatcher is also working fine (Play/Pause works). I noticed that there is a setting in Doggcatcher for "bind to headset" and "start application" - both of which are checked on mine, so maybe that's why it's working.
However, both Pandora and Mog are not working with Play/Pause and there are no headset options in the app settings. So either 1) apps just need to be updated for ICS, or 2) something is amiss in ICS that prevents other apps from using the headset controls. Most likely the latter...
Apparently the developers of Media Button Router have "fixed" this issue.
See here: code.google.com/p/media-button-router/issues/detail?id=10#c5

I can confirm that after installing Media Button Router and configuring to send all BT commands to Spotify - I no longer have the Play/Pause problem.

that works but EVERY time i hit the play/pause button on my mw600 the prompt comes up, freaking annoying, can we have the app that just does the play pause, i dont wnat it to come up asking me what to play pause.
Sorry to revive but i've got an in-car bluetooth and the AVRCP doesn't seem to work with ICS either.. the first time I click play and the first time I click "next track" on the car after the phone connects, the phone will respond correctly, but will not respond to any subsequent buttons until I press the power button on my phone... It's almost like ICS is sitting on all the commands sent to it's AVRCP like a stack, and when I power the phone (either on or into standby), the next click is executed (without any clicks on the car at the time)..
eg: if I hit "Next" twice and "Rew" once on my car, then every time I tap the power button (between on and sleep), it would execute Next, Next and Rew in that order. I have a lock pattern on my phone too, not sure if that's hampering the AVRCP commands either... only way to get out of this is to turn the BT off on the GNEX then on again.. but it does the same thing after the first succesful AVRCP command again.

Audio randomly stops working

So not sure what exactly is the cause but one thing that sometimes will cause all audio to stop working is Google play music. Sometimes when I start playing music (device speakers, not Bluetooth or casted), the audio will stop working in a few seconds as if all volumes have been turned down but they're not. Music playback is still going. Verified that when this happens no other audio works as well.
In some cases the volume slider does nothing when adjusting (slider can be moved but no change in actual volume output level) and playback is still going and then audio is lost.
Playback control buttons in play music become unresponsive and eventual play music not responding message comes up. Closing app doesn't fix and still no audio in other apps or system. Restarting phone doesn't help either really. Only workaround I have found is to cast to Google home, play for a few seconds on there (which does work) and then disconnect and audio on device is functional again. Sometimes cast workaround works without reboot, otherwise the reboot is necessary.
Anyone dealing with this too? Things I should look into for suspect causes? Any help greatly appreciated.
Edit: now when audio stops on device, things become a bit more unresponsive throughout device and eventually the device restarts on own without the play music not responding message. Power off and restart options via power menu are unresponsive at this time too.

Hi Jason, I have the same issue. When I play music, the upper speaker stops emmiting audio and the lower one suddenly lowers its volume (but the audio is at full volume in the UI). the problem is that is random and also affect the phone app. so if this happen and someone call me I cant hear it.
do you resolve it?
let me know,
thanks

I tested in safe mode and verified it was not a hardware fault. I suspected it was something that happened when I was using substratum and applied a theme to Google play music. Factory reset was my only way to resolve.
Same issue here with my Pixel 2. I notice this behaviour after using a Bluetooth speaker, and disconnect from it. Sometime i lost Speaker and Microphone access to the phone. If i connect back to a bluetooth device, audio/mic in the bluetooth device work's fine.
I i reboot the phone, i regain access to speaker and MIC... until the next time i use a bluetooth speaker. I didn't notice this behaviour until last week. I have this pixel 2 phone for 2 month now.

Universal Bluetooth/Google Play Music problem - looking P2XL specific workarounds

I have a Dension GW52MO1 500S BT (adds BT media streaming to older german cars) that has play control problems just with Google Play Music. If I listen to YouTube or BeyondPod, Neutron etc it works correctly. What happens with Google Play Music is the first couple of seconds repeat over and over again. Also if I stop the music it immediately starts playing again (repeating first couple of seconds of track). I can get it to work by turning off Bluetooth between one and 4 times, each time waiting for it start playing by itself.
This behavior does not occur in our other car that has the Pioneer DEH80PRS.
This problem is a bug in Google Play Music, there is a Google Product Forum post on it
https://productforums.google.com/forum/?noredirect=true#!topic/play/FKxS7t1W1dA
My question is: Is there any tool I can install on the Pixel 2 XL to help me work around this issue? I tried using Tasker to automate turning Bluetooth on and off but it when I do that the repeat 1st second problem doesn't resolve itself like it does when I do it manually.
The Dension does not appear to have a way to turn off the autoplay (resume) feature which I think interacts with the bug in Google Play Music to cause the issue.
Thanks

Bluetooth turns control off very quickly.Why?

Hi!
I have tried two headphones (Sennheiser M2 IEBT and Focal Listen Wireless) and two audio players (Youtube Music and BlackPlayer) and got the same result: after toggling a pause on headset any attempt to resume a playback after a couple of minutes results in nothing. That is Bluetooth control is lost. I'm forced to take a phone, unlock, start player and start playing back.
It is interesting, with Huawei MediaPad M5 8.4 I don't have the problem regardless headphones and players: Bluetooth control is kept at any case.
The most performant mode is selected in battery settings. The last official firmware (169) is installed.
Please, help me to resolve this very annoying issue!
I've noticed that when I play media content using a third-party app and then pause it from a Bluetooth device, sometimes that app gets terminated in the background and when I try to resume, it starts playing from the stock EMUI music app instead.
Although I haven't tried this, disabling battery optimisations for your music apps might prevent them from being terminated in the background.
Yes, all battery optimisations for players are disabled. Also, a lock was activated for players on recent apps screen.
I have tried a couple of settings on the developer configuration list (amount of background processes and amount of Bluetooth devices), but was not lucky.
Ok, can you, please, share your experience in having or not-having described problem?

Deeper Alexa Integration Into Android Auto

Hi All, I've done some googling but I haven't quite found the right answer to my question. Right now I have a Viva Roav Pro in my car and a Android Auto compatible head unit. If I ask Alexa to play music either via the steering wheel controls or the Roav, music starts streaming via the Alexa app. However as the Alexa app isn't one of the music apps with Android Auto integration, Android Auto doesn't offer controls to skip tracks etc - worse, if you try to, music will stop streaming and Android Auto will take over with whatever was playing last on Android Auto.
As I use Amazon Music and have the app, which DOES integrate with Android Auto, all I really need is for Alexa to open and play my request from the Amazon Music app as opposed to the Alexa app, but I've not figured out a way of doing that. Anyone else got any ideas?
