garage band is not picking up audio from my audio interface. I’ve set the audio inputs and outputs to the same thing and still nothing

Hey there Bigmoo38,

Thanks for reaching out to Apple Support Communities. We'll be happy to help. The issue could be related to the devices you're using with your Mac. If that is the case, you'll want to work with the manufacturer to troubleshoot those.

For GarageBand on your Mac, follow these steps:

If you can’t record audio on a Mac using macOS Mojave or later - Apple Support

1. " Quit the app you're using to record audio.
2. Choose Apple menu  > System Preferences, then click Security & Privacy.
3. In the Privacy pane, click Microphone.
4. Select each app that needs access the built-in mic, an external USB mic, or the inputs on an external audio interface.Open the app and try to record audio again. 

(If you're using an external mic or audio interface to record audio and it's still not working, check with the manufacturer of your device for software updates and information on compatibility.)" (Retrieved from article linked above)

Take care.
