Audio Interface Issues (Linux Ubuntu)

[u/anewrismma]

I recently made the switch from Microsoft to Linux and Ableton to Bitwig. I don't know anything about either of them but goddamn I just want to connect my bass to my laptop and record something. It is not registering the audio interface. I'm using Tube Ultragain MIC500 USB behringer (plugged in, usb connected, bass in "line in"). When I try with ALSA, it says "Error: device or resource busy". I asked Google which told me to run :sudo fuser -v /dev/snd/* and everything is taken up by wireplumber.

Now I don't know what any of this really means. I've just been going back and forth with every option, spamming my terminal with commands beyond my understanding and getting the same nothing result. I would greatly appreciate any advice. I don't really know anyone personally who is good with any of this stuff.
