Can't record line-in audio w/ Quicktime

Hello AV2008,

After reviewing your post, it sounds like you want to record sound from iTunes using Quicktime. Do you have a microphone plugged into line in? I would recommend that you read this article, it may be able to help the issue.

How to use QuickTime Player - Apple Support

To change the recording settings, click the arrow next to the Record button. Then choose your microphone and recording quality.

Thanks for using Apple Support Communities.
Have a nice day

So I guess I can 't record just anything coming thru my speakers, just sound from a microphone, correct?

That is correct.

There are third party apps that will do that for you.

Audacity and Soundflower can do this:
