[MPlayer-users] a few notes on AC3 passthrough in general (was SBLive AC3...)

[Aubin Paul]

This may be offtopic, but did you manage to get standard PCM and optical 
to work concurrently? I currently have to switch asound.state files for 
it to enable AC3 passthrough... it's not perfect, but it works. For that 
matter, have you tried anything newer than 0.9b10? My AC3 passthrough 
broke with 9b12; if you feel like providing your asound.state that would 
be nice too.

(to make a asound.state, do "alsactl -f asound.state store"
