I think that you're getting grub device names confused with alsa names.  
Normally you can address them by hw:0 or hw:1 or hw:2.  Basically hw:0,1 for 
capture device and hw:0,0 for playback.  You can give more meaningful names in 
your .asoundrc configuration.  But generally NOT HD#, that's a grub thing for 
Hard Drive.  Although most alsa apps reference them by -c # where the # matches 
their designation in /proc/asound/cards.  Many apps that use alsa use something 
like -D hw:2 or -ao alsa:device=hw:2 and that is assuming that you don't want 
to just use the defaults.
