USB audio codec selection

How/where can I select Audacity app > Device > Sound Settings > USB Audio Codec. I can’t find it in the options. I can only find ProTools options, which app is not in use. MBPro M1/ Ventura

I dont know the macOS, but your USB audio needs to be installed and setup as an audio device in any operating system first. Then it will appear as a selectable device within Audacity and to use it in Audacity just select it…if it is a mic then audacity sees it a recording device…if output sound card/ speakers audacity sees it as playback speakers etc.
