Question Trouble using Arecord to record audio with new Zoom U44 interface


I bought a new Zoom U44 audio interface, and I can't figure out how to get it working with Arecord.

More specifically, I can't figure out how to choose which input on the interface I want to use. This is the command I'm using.

arecord -D "plughw:CARD=U44,DEV=0" -f cd Test.wav

It makes a recording, but it contains only silence. I assume that it's trying to record input 1, but I need to record inputs 3 and 4. I'll post the output of "arecord -L" in case it's helpful.

Scratch everything I just said. I had to adjust the gain in Alsamixer.
