Thanks. I just downloaded vom wmv test files from http://www.microsoft.com/windows/windowsmedia/musicandvideo/hdvideo/contentshowcase.aspx and created an .asoundrc: pcm.ac3 { type a52 channels 6 slavepcm "hw:0,0" } So far so good, I now run mplayer -ao alsa:device=ac3 -channels 6 ... but the sound is a bit strange. One files has the speaker rear left, one other file does not use the rear speaker at all. Someone an idea how to make it right? Next question: if I have less than 6 channels in the media file, can I still use -channels 6 and the defined pcm device in my .asoundrc? I tried playing a mp3 file with that settings and it is using the left and right front speaker as it should be. It would be nice if Freevo 2.0 (or in this case kaa.popcorn) would support such stuff.
