Bug? SetVolume and Android 12

[FredL41]

Hello,
Since Android 12 the SetVolume method no longer works when my application is in the background. No problem with Android 11, Android 10 and Android 9.
Am I the only one having this problem?
How to solve it?
Thank you for your help.

It might be a new restriction in Android:

Why volume is not changing when app is running background?

This app is working fine when the app is opened or the app is on the screen. Volume is changing when app activity is opened. But when app is running on background, volume is not changing with slide...

Try to request audio focus before starting playback: https://www.b4x.com/android/forum/threads/audiofocus.53295/post-334224

Hello Erel, thank you for this solution. I get the audio focus back but still can't change the volume in the background. No big deal, I can do otherwise by recovering the audio focus. But how to abandon this audio focus?
Thanks in advance.
