So are you saying that if I choose the correct dmix device listed via:   
aplay -L on my system I can get desktop sound to work via HDMI output?For  
instance,something such as:
pcm.!default {
	type dmix
	card 1
            device 9
}
in asound.conf.I think I may have tried those variations,but it is  
possible that I didn't.
