I have noticed in Plexamp that there are two audio interfaces: OpenSL ES and AAudio.
I had problems with OpenSL ES on my Pixel 6 with Android 13 so I switched it to AAudio and then it worked perfectly.
Would it be possible to use the audio interface from google called Oboe?
It uses the new AAudio for new devices and OpenSL ES for older devices.
So everyone should get the correct interface for their device by default and you don’t have to switch them anymore.

Apparently it also has some features to avoid common audio bugs.
You describe OpenSL ES in the app as the secure stable choice. That is the reason why I selected it. Maybe you should change the description to Legacy Interface or something cause for most users nowadays AAudio is the right choice.
