The problem is still occurring.
Sound works, but a decent listening volume level means - all controls
have to be maximised. But even now, the sound is not loud, just "normal"
small quiet room level. I am outputting sound through my stereo (line
in) and have the stereo set to a normal volume level (always been
perfectly OK).
I currently run Gutsy (I wrongly said Feisty above).
The sound problem was in Hardy when I updated a few months ago, and in Intrepid
when I first tested it. I have reverted to Gutsy for now.
Note however - I have purchased a Soundblaster PCI card (which I removed
for this re-test) and this works much better. So ... I will just stop
using onboard audio and ignore this issue.

Shuttle SG33G5 is on the latest BIOS. However, unless I boot with kernel
option "acpi=off", I hang at boot.
