Today I tested starfox in snes9x ex + an it crackled too but after setting audio output rate to 44khz instead of 48khz the popping was gone.
I think some android devices don’t report there real frequency and just report “48000” regardless and then down/up scale it from there.
This problem also happened with the video where certain devices OS would say “60fps” when it was 58.1fps.
Could an option be added to manually set the sampling rate?
