On this exact note - I was having trouble just today with a recent SVN release attempting to do 5.1 native from myth the analogue route.
I have a HD5000 that records a few streams with 5.1. I also have xine setup to use the analogue 5.1 outputs to drive my receiver for dvds. Now in myth, when I change from ALSA:default to ALSA:surround51 (which I use for xine), I get no audio in myth. If I try to force it to the exact pcm available for my card, ALSA:hw:0,3 I also get no audio. Is there something else I'm missing here?
