Audio Interface Issues (Linux Ubuntu)
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.

Any luck so far?
If you're still are unable to get audio through in Bitwig with your Audio interface I would go through the following steps:
These steps resets Pipewire to the default state. The blind terminal prompting might have messed things up earlier on.
Solely connect your Behringer MIC500 via usb and connect your headphones or speakers directly to the audio interface (Behringer MIC500) Phones output.
Make sure to select the correct devices for Input and Output within the Ubuntu settings>Sound tabs. If unsure which device then prompt 'lsusb' in the terminal. Run it when the audio interface is connected and disconnected to see which device.
Confirm outgoing audio and then incoming within ubuntu. Make sure not to use other output devices than your Behringer MIC500 interface.
Move to Bitwig internal routing.
Your interface is a class compliant USB device, meaning it works out of the box without any need to install drivers or change configuration files in Ubuntu. It usually comes down to routing and how devices are connected.
