When paplay is hanging there is no audio from any program. If I run something
(aplay, speaker-test) via pasuspender then that program can play audio fine.
When pasuspender exits, programs that are trying to play audio all unhang and
play normally. But once the device suspends again, we're back to square one,
where any thread trying to play audio hangs again.
