MME input not working right....HELP

I record music. I just recently got a new Dell to use specifically for recording. In the past using Audacity, to record guitar tracks, I use the MME input with a Marshall Code 50 amp with a USB input, and have had ZERO issues. With this new laptop for some reason I start recording, and the signal cuts at 2 seconds. I did nothing different that I have done in the past. I even had the firmware on the amp updated. I tried lowering the input volume to no avail. Is there some tweak that I’m missing? Any help or advice would be greatly appreciated. Thank you in advance.
