I'm vainly trying to get chuck to work with my Via Epia CN10000EG in 5.1surround sound. It's running XP SP2. I'm able to play 6 channel audio files using mplayer. When I probe for audio devices I don't get any 6 channel capable devices: =========================================================== [chuck]: found 4 device(s) ... [chuck]: ------( chuck -- dac1 )--------------- [chuck]: device name = "Primary Sound Driver" [chuck]: probe [success] ...
