2.6.34-stable review patch. If anyone has any objections, please let me know.


From: Daniel T Chen <crimsun(a)>

commit 26fd74fc01991a18f0e3bd54f8b1b75945ee3dbb upstream.


Symptom: On the reporter's iMac, in Ubuntu 10.04 LTS neither playback
nor capture appear audible out-of-the-box.

Test case: Boot from an Ubuntu 10.04 LTS live cd or from an installed
configuration and attempt to play or capture audio.

Resolution: Specify the mb31 quirk for this machine in the codec SSID
