[Android] While a game is loaded with mupen64plus on RetroArch, returning from phone sleep and switching apps Crash or Black Screen RetroArch

[fireflamesniper]

This is a bug I have noticed for quite some time with various devices running Android. If you switch apps / go to a recent app and then back to retroarch/ Come back from sleep mode to RetroArch, RetroArch loaded with a game with Mupen64 will either crash (noticed with various Samsung phones throughout the years) or comes back to a black screen with the audio still playing but none of the controls work (Happens on Retroid Pocket 4 Pro).

Seems the audio driver stops which i guess could cause some unexpected behaviour inside of RA
Can you check that 1. it doesnt occur with NULL audio driver, 2. it doesnt occur with "pause sounds in menu" (cant fully recall the name of the option) @fireflamesniper

For what it's worth, it's the same issue on a Mali G68/Android 11 device here. retroarch.log

Happens to me too since forever on a Realme 7 5G which uses a Mali-G57 MC3 using the Vulkan driver/renderer.

Retroarch version: 3ab3b32.
Android version: 12

Here's my log, retroarch.log

And a screenshot:

I'm also having this problem, all default settings, playing on Samsung S24 Ultra, Android 14.

Crash log is here: https://pastebin.com/1dkvdsSm

I've noticed that this is specific to this core. This issue doesn't happen when using ParraLLEI, but that core has a host of other problems which make it a less ideal choice than this one.

I hope you can solve this problem at some point, I really want to play without worrying about that eventuality and losing a game in the process.

If there ever is a solution, this issue will be referenced as is appropriate, so no need for re-pinging active threads that the maintainer has already acknowledged (unless you have something to contribute to the conversation or the problem, ofc).
