We've found a way the can reproduce the problem more quickly on our
product:
- do audio playback
- alsamixer, select 'Master', press 'm' and hold for a while.
Then release 'm', playback corrupts(sounds similar to http://dev.lemote.com/files/upload/software/PA-apc/corrupted_sound.ogg).
Is the output supposed to be playing or muted at this time?
Playing
This appears to be a problem with PA's volume handling. It might be caused by incorrect dB volume information of the HDA codec, or by a bug in PA.
What does rewind do? Why we need rewind here?
It allows to rewrite already written parts of the audio buffer; it's used to apply the new volume to samples that have not yet been actually played.
