Registration Problems

after downloading audacity and the driver for my interface audio (behringer u-phoria umc 22) I immediately started recording. The next day, after opening audacity, I notice as soon as I start recording that no waves are emitted, so I wasn’t recording anything even though my guitar was connected to the sound card and the latter was connected to the computer. Even if I check that my interface audio is connected, it also doesn’t record while I play.

Make sure to select the USB device as your [u]Recording Device[/u].
