Need help with a USB sound card

My computer does not have a built-in sound card, so I use a USB sound card instead. When I plugged in the USB sound card, its audio output had a lot of noise and the sound was not smooth. How can I fix this issue? I am running Debian 10, and here is the info on my computer when the USB sound card plugged in:
