A quick Q. A friend is building up a little linux box for testing apps. (He's putting his toe in the linux waters for the first time.)
He'd like to use a cheap usb audio unit for sound. Any reccomendations, or experiences?

He did mention he was looking at some sort of Behringer unit.

I appreciate this is a vague Q, but he's looking for something stable, rather than cutting edge.

Any help or tips would be appreciated.

Alex.
