Was the output of alsa-info.sh useful for anyone to assist me with this issue?

Unfortunately, I have no idea what "a missing EAPD via COEF commands" means!  :-)  I know Tobin had replied offering to help out with this issue as well - perhaps he'll be able to do something with that?  I'll glady do anything asked of me (that isn't over my head), such as compiling from hg sources with debugging enabled and sending along output, etc.
