I use kubuntu 7.04 on a dell dimension 2550. It has an intel sound chip on the motherboard that I have running just fine.

I have just picked up a new cd player/clock radio and it has a USB port which, with that other OS, is supposed to be able to play sound produced by the computer and to play back the sound it produces on the PC.

At a console, I get:

I believe the JVC unit is Bus 1/Device5

USB Viewer, won't let me copy its output, but it says

USB Audio DAC
Manufacturer Burr-Brown from TI
and quite a bit more information.

I would like to play all of my sound through this unit but I have no idea how to set it up. Is it something that is windows only?

Is there a way in kubuntu to add another sound device like this and be able to switch between them?
