Public bug reported:
No sound at all after fresh install of Xubuntu 11.10 on MacPro 5.1 with Intel
HDA sound card and Realtek ALC889A chipset.
Google told me to modify /etc/modprobe.d/alsa-base.conf and add
options snd-hda-intel model=mb31
to fix problems with the ALC889A but that didn't change a thing
Modules are loaded and aplay -l lists all devices nicely
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC889A Analog [ALC889A Analog]

But no sound at any plug. And no error message as far as I can see.
