Hi Jim. Yes it was connected and switched on. I could see it in the audio settings as USB Codec or something like that in both BIAB and RB but just could not get it communicate. Got home and disconnected the Alto. Took a test mixer from a friend. Its a Wharfdale Connect 1202 plugged it in and switched on. Set the audio to the USB PnP and wow works perfectly. Go figure. I thought I had the better mixer. It cost dubble the price of the wharfdale. Anyway now I'll do some wheeling and dealing and experiment with the Wharfdale. Thanks and take care. Bryan.
