/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 (
). It has much more descriptive (and instructive) comments.
