As it happens it works in ubuntu 10.10 out of the box. I only need to go
to the sounds preferences and switch cards and sound is routed to the
soundbar. Both the media controls (volume, mute) on the laptop's
keyboard and the volume knob work.
I'll see if I can get it to work in squeeze by comparing the
configurations.
