Hi Vic,
Looks like you have things set up. Tnx for including config pictures!
Try using alsamixer, open it in a terminal. Use F6 to select your card. Use F5 to toggle between output/input/all and MAKE SURE it isn't MUTED.

At one point, I had an update and for whatever reason, it muted my USB audio. Grrrrrr once unmuted, all was lovely and birds sang, clouds parted, folks danced in streets.
