Audacity 222,Win.10 .Sound Interference

Hi, I am getting a blue line and noise instead of what should be coming through USB when I record through mixer.I am using UCA222 USB interface into Win.10 Lap Top.(Pavillion).I had previously tried a downloaded version from a Disc which gave me the same problem (an earlier version of Audacity).So then I downloaded the Audacity 222 version.When recording without USB connection I get the same line and noise …though a lot quieter.

Can you help.
