Myth's ALSA audio output support is basically just a (series of?) 
hack(s) to extend the original OSS audio output support and was never 
fully developed.  The fact that the current code presumes that all audio 
cards have a Master and PCM control (which is not true in the case of a 
large number of Intel-HDA-based sound cards) is another anachronistic 
assumption that should eventually be fixed with a big refactoring of the 
audio code.  (Note that I did not say a "planned refactoring.")

Anyone wishing to do said refactoring would make a lot of people happy.
