Public bug reported:
Dell Dimension L700CXE desktop, was running 11.05, but on upgrading to
11.10 and then to 12.05 the sound device has vanished; the modules are
loaded, the device appears in lspci, but on the sound config Output or
Input panel there are no devices listed and the output volume slider is
greyed out.
it must be something simple I'm overlooking, because so much of this
looks perfectly normal. All users are added to the audio /etc/group
