hmm, weird.
it means the bug is somewhere in audio out.
what ao driver are you using?
show me whole -v log of pcm playback on ppc

hmm. even more strange than...
if this works, then it should work for ad_pcm too

there are known issues with the ac3 decoder on ppc

no, it's not my code, but atmos will check it, i'm sure

should be easy to fix
