Thanks Paul. I've been using model=acer and I just tried a couple others, some worked some didn't. I also tried removing and replacing my second USB sound card definition. The strange thing is I've come back to my original config and it's working now. Could another file have gotten out of order and my playing with the settings got it back together? - Grant
