/You/ shouldn't use digital-hw; it's OK for the .asoundrc to use it (in 
the definition of the default device).  Once you've done that, you use 
"default" (or, for some applications (not Myth), just don't specify a 
device and the default device will be used).

If you don't have it now, get the updated config file from the wiki ( 
http://mythtv.org/wiki/index.php/Configuring_Digital_Sound#Setting_up_ALSA.27s_.asoundrc.2C_Properly 
).  It has much more descriptive (and instructive) comments.
