Audio stutter when device sleeps on Android

Is there an existing issue for this?

• This is a bug in RetroArch frontend
• I have searched the existing issues

Description

On the Android version of RetroArch, when I press the device power button to put my device to sleep while a game is running, the audio briefly stutters instead of stopping immediately when the screen turns off.

I'm using the VBA-M core with the OpenSL audio driver- I haven’t tested other cores yet.

Expected behavior

Audio should stop cleanly as soon as the screen turns off.

Steps to reproduce the bug

1. Launch RetroArch on Android.
2. Start a game with audio (I am using the VBA-M core with the OpenSL audio driver)
3. Press the device power button to put the phone to sleep.

Relevant log output

Start by reproducing the issue on Android 11 with the VBA-M core and OpenSL audio driver while monitoring the transition into device sleep. Trace the Android sleep handling and OpenSL audio path to determine why audio continues briefly. Done means audio stops cleanly when the screen turns off and the behavior is verified with the reported setup.
