First use modules. This post [1] from the forum is about the mic but
it walks you through the process of setting up sound pretty well.

My reading of those errors implies that you might have an alsa config
file left over which is confusing mplayer. Make sure that you don't
have .asoundrc or .alsa* in your ${HOME}. You probably don't need one
(not for most setups).
Is your card in `cat /proc/asound/cards` or alsamixer ? (can't check
correct location, in Windows atm).
