"Chipmunks" sound implies that the audio is being played back at a
higher sample rate than it was recorded at. Obviously this should not
happen if all layers are aware of the recording sample rate and adjust
playback accordingly. So you would need to find out what part of the
system is using (or guessing) the wrong sample rate.
It could even be that the problem is right at the end -- if pulseaudio
is outputting 44100Hz and the hardware for some reason is playing at
48000Hz. Perhaps even a hardware fault if not software. You would need
to establish at what point the wrong sample rate or conversion has been
chosen. Sorry I don't know the commands for that...
