I have launched the command alsamixer, but I am unsure of what you mean by if it is listed or not. What I can see is:
Under Gnome in the top "bar", I have a small icon for the sound. On mouse over, it states "Master: 22%" Under Gnome, in the Sound preferences window, I see "Device: Intel 82801DB-ICH4 (Alsa mixer)" Under alsamixer, I see: "Card: Intel 82801DB-ICH4" and there is one control for a "Master" which is on 23<>23 I have a Gnome bugzilla account and I will report this bug there. -- Sound is displayed as mute after suspend/resume whereas it is not https://launchpad.net/bugs/90341 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
