Question

Everything seems to work correctly except recording when using the USB cable. Using the RCA to mic in and headphones out  works through the mixer fine.

Answer 1

If using USB you'll want to go into audio settings (CTRL [Period] ) and verify your input and output configuration.

Answer 2

I did that. I am actually getting a signal from the microphone into to meters but when I record nothing is being recorded. I can play back a recording so I know that is set up correctly and the mic output shows that to  be correct as well. As I said I can change it back the using the RCA cables at it records that way. I have tried on two different computers to so I must be missing something.
