Audacity 3.7 doesn't receive signal from mic routed through interface

Audacity recognizes my interface (Focusrite Scarlett Solo), and the interface gets the signal from my XLR microphone, but the mic signal isn’t making it all the way through to Audacity. My PC settings for input and output point to the interface, but Audacity doesn’t show any audio signal at all when I speak into the mic. I’ve read other similar topics, but none of the recommended fixes are working. Thoughts?
