Excellent help Richard. I am now enjoying old rock and roll music via my us122 now, thanks to your advice. I think it might even have defeated the problem about the us122 only starting sometimes. DVDs and CDs playing OK.

I was getting rather put off with Ubuntu having had problems with my scanner, printer and the us122. Now I feel like continuing with the struggle.

Next step might be to get midi working.

Cheers

Jay
