Sound card is no longer detected in the latest upgrade, "dummy output" every time when I reboot the OS now for me. Saleh's fix in comment #16 from https://bugs.launchpad.net/bugs/1169984 did NOT fix my problem. The kernel from #17 from https://bugs.launchpad.net/bugs/1169984 did NOT fix it for me neither.

Though somethings failed, then the sound setting options come back, the mic works, after I restart the X window, I can hear the voice, but "dummy output" again when I reboot the computer.
