[ubuntu-uk] Lost all sound after upgrade

[Helen McCall]

Can anyone point me to whatever might be causing my sound problem?

I performed a long overdue upgrade to a number of packages. Following
which my sound just stopped working altogether.

The offending upgrade was the following:

libxine1c2 (1.0.1-1ubuntu10.2)
linux-image-2.6.12-10-386 (2.6.12-10.26)
linux-restricted-modules-2.6.12-10-386 (2.6.12.4-11.1)
plib1.8.4 (1.8.4-1ubuntu1)

After this I attempted to play a wav file using totem-xine. This sort of
played, but very patchy. I then tried audacity but could get no sound at
all. after this I could not get any sound of any kind. No sound from the
gdm login screen, or from the gnome desktop, or from any sound
application at all, however I launched it.

I tested the es1371 soundcard by booting up an old installation of
Debian 2.2 potato. The soundcard worked fine and everything was fine in
potato.

Booting back into Breezy I checked that the alsa server was running. I
ran a sound test on it, which apparently ran, but produced no sound.
Everything I have checked appears to be correctly setup, but just no
sound comes out of the speakers unless I boot into the old potato
installation. 

I am totally mystified for the first time in a decade of using Debian
based systems.

Can anyone help?
