This might be a trivial question but I am having trouble configuring xine and mplayer to play multichannel audio (from a DVD) through a RME-Multiface configuration. Two channel output (stereo) works fine. I have tried setting xine to "5.1 channel output", etc...but nothing seems to work. I know the multiface works as I have written some simple code to send audio to the 8 analog channels. Any help with configuring Xine/Mplayer would be much appreciated. DS
