Quick testing with auto-mute in alsamixer resulted in the following
behavior:

1) before using alsa mixer, after a suspend-resume, audio didn't work
2) enter alsamixer, auto-muted was enabled
3) set auto-muted to disabled, random "synthetic-fart" noise
4) open browser, go to youtube, turn up the volume and audio works
5) set auto-muted to enabled, audio stops working
6) set auto-muted to disabled audio resumes
7) stop music, suspend, resume, audio keeps working

Just for completenes, my machine is an iMac 9,1.
