So my wild guess was right, then? There was a clue in that the USB device was being allocated as sound card 1, with no sound card 0. As I posted a few weeks ago, it's probably a year or more since I had any sound trouble, and I'd forgotten that the count was 0-based. But it's good that there's an easier way than buying another sound card. I'm pushed for time right now, but I'll try this later today. -- Joe
