That seems to indicate that some other program is using your sound 
device.  Since you've set a default of "unmixed" digital, only one 
process can use the sound at a time.  It seems Myth won't do playback if 
it cannot get access to the sound device (which is exactly what it 
should do).

Therefore, try "mixed" digital as your default.  Uncomment this line 
instead:

## Uncomment the following to use mixed digital by default
#  slave.pcm "dmix-digital"

Note, you will need to restart the program that is currently using your 
sound before this will take effect (because it is still using it 
exclusively).  The easiest way to ensure this happens is probably to 
reboot after changing your .asoundrc.

Good luck,
Mike
