Audio inout only works if no other app requests it (w/ possible solution).

[Slluxx]

For example launching discord works just fine but then launching an app that wants to capture audio input, it gains control over it, leaving discord to recieve only silence. This has been by design on android but there have been changes since android 11 that could maybe fix this.

As per https://stackoverflow.com/questions/4495122/sharing-audio-input-on-android
You can also use

MediaRecorder mRecorder = new MediaRecorder();
mRecorder.setAudioSource(MediaRecorder.AudioSource.VOICE_UPLINK);

However, i dont know how much success it yields.

I hope this gets explored so we can talk to friends in discord while playing other games.
