So apparently having both the realtek and the nvhdmi codecs compiled in is a "bad idea" ? With just the nvidia one compiled in I can play via mplayer with: mplayer -ao alsa:device=plughw=0.3 test.wav And if I add the following to ~/.asoundrc I can play with just "-ao alsa" and know magic device naming. defaults.pcm.!device 3 And in MythTV I am even able to do multi-channel audio passthrough for my AVR to decode. Very cool! This seems to mess up aplay -L though, as it will no longer list the default pcm, and only lists the null device - even though things continue to work. Can anyone explain that to me? So for my last effort of the night I'll turn off debug and see if it still works :) Then I'll yank that phones to RCA cable out of there and FINALLY by completely digital! -- Darren Hart ------------------------------------------------------------------------------ _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
