Constant sound?

I am using a u control behringer uca222. I am using a macbook air with a an apple usb - usbc converter into it. I am certain that it is picking up my sound, but when I press record, the recorded sound maxes out to 100% despite it not being nearly that close sound wise. This is my first time using a behringer or audacity so if I’m missing something please let me know. When recording with my macbook, the noise recording is normal.
