Public bug reported:
I'm a new Linux user. I installed Ubuntu 6.1 some weeks ago, but noticed
that on boot-up the sound would sometimes fail to work. A reboot (or
several reboots) usually fixed the problem. Two days ago, the sound
failed completely. No amount of rebooting restores it. I've worked
through the suggested fixes described at
http://ubuntuforums.org/showthread.php?t=205449&highlight=reinstalling+alsa,
and although my sound card is detected (see below) and I have removed
and reinstalled the ALSA drivers: linux-sound-base alsa-base alsa-
utils, I still get no sound. Nothing is muted in either the ALSA control
panel or the regular volume control panel.
The only change on the system prior to the complete sound failure was
the latest Ubuntu update. Unfortunately, I can't recall what was
contained in it, but the sound went after this installation.
