Correct, it's now muted. Now you need to try different settings of the 'IEC958 Playback AC97-SPSA' element,
e.g., amixer set 'IEC958 Playback AC97-SPSA' 1 or amixer set 'IEC958 Playback AC97-SPSA' 2 or amixer set 'IEC958 Playback AC97-SPSA' 3 -- no sound at all. Even unmuted https://launchpad.net/bugs/58339 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
