No volume control GStreamer plugins and/or devices found.

This is the error I receive when I try to open my 'Volume Control'
(there's no volume)

I'm using Ubuntu 8.04 LTS Desktop Edition

Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller

It's a bit labourious but try reinstalling your sound packages and see what happens. I had a similar problem about two days ago when I was un-installing loads of packages. Nothing appeared to be missing to me, but I did that and reset the system and my sound came back. I can't be certain that that will definitely solve your problem but it's worth a try I guess.

Maybe someone else will have a better solution.
