I have a problem

I plugged in my microphone into my computer, but Audacity wasn’t recording any sounds, even songs I was just playing on iTunes. I think it might be that I turned something off. The only thing I can this of is this: It’s that notification when you plug in the microphone that asks you to choose which external device you want to use & gives you a list of devices. I said that I don’t want them to notify me anymore, so this might be why?

Any suggestions would be helpful; I really want to use Audacity! :unamused:

You need to give more details:

What are you trying to record, your microphone or sounds playing on your computer (iTunes)?
What operating system are you using?
Which version of Audacity?
What sort of microphone.
