Summary: Audio crackling via s/pdif

Initial Comment:
I'm getting some audio crackling when routing sound via 
the digital jack on my SBLive (ALSA drivers). This 
happens repeatedly at specific points of the audio track 
(it appears to be at times when low bass effects are 
used).

I get the same result on the analog outputs if the PCM 
volume it too high, but lowering that to about 60% fixes 
the analog problem. Lowering the volume on the digital 
mixer controls does not get rid of it, but I expect the 
root cause is the same.

The source material plays fine on other systems, and 
mplayer handles it fine. The digital connection, receiver 
and speakers are also obviously fine if mplayer handles it.

I've taken the mp3 stream and converted it back to a 
wav (on another machine), but playback of this wav 
gives exactly the same results, so it's not a problem with 
the mp3 decoding engine.

I've also taken that wav file and played it with aplay to 
test the ALSA configuration, and this plays fine.

Passthrough of AC3/DTS streams works perfectly.

Overall, it looks like xine's audio output is overloading 
something, but I can't think of anything else to test.

Maybe some amplifier or mixer setting in xine is too high? 
Could you delete or rename the ~/.xine folder to make sure 
you have a clean configuration?
