Makes sense, but I don't really understand the instructions...
-delete the file - done
-reboot - done

$ alsa-restore.conf:exec /sbin/alsactl restore -f

$ alsa-restore.conf:exec: command not found

I have /etc/init/alsa-restore.conf...what did I miss?  By the way, alsamixer doesn't run now...not sure when that happened.

don at zedo:~$ sudo alsamixer
cannot open mixer: Invalid argument

While I was experimenting, I came across a suggestion to remove pulseaudio

$ sudo apt-get remove pulseaudio

After removing it, the audio in chromium (flashplayer) started working.  
Tried the movie trailer player in Myth-netvision, but still no audio.
