Sound not recording

Hello, I’m wondering if someone can help me. I recorded on Audacity last week and everything went fine. Today, I tried to record on Audacity and it just didn’t pick up the sound. I checked everything. I made sure my security settings were okay (by clicking on the microphone icon and checking that box next to Audacity was checked). I checked that my microphone settings were on and that USB was acknowledged.Now I feel like I’ve run out of options and every forum I check, just seems to suggest that I check my security settings.

Welcome to the forum!

What’s your setup? Microphone, interface…

Does your microphone need phantom power? Is it off, by chance?

Just a hunch, of course…
