Nigel, Well, as I said in my private email (forgot to include the mailing list), I connected up my USB box, and can now both record and play back using arecord and aplay. So the problem seems to be in the configuration of the SB sound card. It was a cheap OEM one, so probably isn't well supported anywhere. I wish I'd had the courage to try the USB box first, but was a bit worried about having 2 cards configured and wasn't sure about USB in Linux. As I'm more interested in the USB box, I think it's best to close this thread, and thank you very much for your help and encouragement. Now for some quality tests.
