1 [UA100 ]: USB-Audio - UA-100
Roland UA-100 at usb-00:07.2-2
So it looks like something is seen but how do I get aplay to play to the
UA-100? The VIA card has alway's reported itself but neither windows,
linux or anything else has ever got any life out of it!
so do I use the aplay to select the card even thou, aplay -l doesn't
list it?
