2.12.10.6 changing my non-bt media volume on device disconnect

[snowman386]

I have a nexus 6p with 8.1 dec 2018 security patch. The latest version 2.12.10.6 has been lowering my media volume after disconnecting from a BT device. Stopping the a2dp service eliminates the problem.

This is by design. It captures the volume before any devices connect and volume is restored to that level after all devices disconnect.

Sorry but this is not true. I have media volume set to 100%. Then I connect to my car's bt which is an a2dp device. A2dp ensures that the bt media volume is 100%. After disconnecting from my car's bt, the media volume is lowered to somewhere between 50-75%.

I have used a2dp for quite a while. This behavior is new since the last update. As I said, it appears to be an a2dp issue because if I disable the a2dp service, my media volume remains 100% after disconnecting from the bt device.

Please reopen.

I'll see if I can reproduce this issue with the latest version.

You can also simply install an older version if you preferred it. These are available here: https://1drv.ms/f/s!AgUbpiol3wYLux6pg4EQ-ee8sGci

Also I have had similar complaints recently and it appears many other apps and OS features are now also controlling the volume. This has been verified on some devices already.

One other thing, the timing of the volume change matters. Make sure you have a good volume adjustment delay. Try a few different settings.

As there are many different volumes on different devices and many OS and app feature also adjusting volume it gets very tricky to make this work correctly. Also, Pie handles the volume going forward so the volume adjustment features will be removed on Pie and up.

Updated to 2.12.11. Still the same.
Set media volume to 100%
Started car which caused bt to connect. Everything is fine.
Turn off car and non bt media volume get set to ~60%
Repeat the procedure with a2dp service stopped and media volume stays at 100%. I thought it may be the remember volume setting because I had it enabled on 1 device and the last bt volume was about the same level that my media volume keeps getting reset to but that didn't fix the issue either. Now no devices have the remember setting enabled. I will probably rollback for now. I use android auto via bt all the time but I don't like having the nav audio go through my speakers so I use the phone speakers for google maps. This uses the regular media volume which keeps getting lowered to barely audible levels by a2dp.

I can confirm this. It looks like a check for !mvolsLeft was added to getOldVol and this is keeping the previous volume from being captured. When I remove the mvolsLeft check it does set the volume to where it was before the connection. Not sure why the check was added there.

That was added to fix a problem I was having where I had 2 devices simultaneously connected. The first would connect, set the volume, then the second would connect but it would grab the now adjusted volume and capture that as the volume to use as old volume. Then the volume would always stay high because old volume was capture incorrectly. I added a check (as you described above) to ensure no devices were connected before capturing old volume. This makes me think the user with the issue has a device connected pretty much all the time so it can't capture an old volume.

@snowman386 what is your desired behavior? It is not clear from this thread. Do you always want your media volume to stay at 100%? Also, based on the description of this thread, it seem like your concern is that different volumes are being adjusted on connect versus disconnect? Is that the issue? Please explain your use case and desired behavior. By the way, Waze has a feature where you can have it set the volume to a desired level for navigation instructions and so does Google Maps. This was for the use case you describe actually. Have you tried that? .

I want the app to stop arbitrarily lowering my media volume. I don't have multiple Bluetooth devices connected simultaneously. I use a2dp to start apps on connect and to adjust the Bluetooth volume for specific devices. I don't want it to lower my media volume on device disconnect. It should leave my media volume unchanged on bt device disconnect.

@snowman386 OK well that is not how this app works. It sets the volume back after all devices disconnect by design. The only reason it was giving behavior you liked before was due to a bug in capturing old volumes. Now I fixed that.

You can clone the app and build a version that does what you want. By the way, On Android 9 an up I removed the volume control feature all together since Android now has this built in. As soon as you get Android 9 and up the volume adjust feature in this app is disabled. For now, just use an old version with the bug that gives the behavior you are happy with.
