Screen recording w/Quick time

to record the mac's internal sound with quicktime you need additional software. i use the free BlackHole Virtual Audio Driver. then you can choose "BlackHole 2ch" in the recording options instead of "Built-in Microphone."

you will also need to set up a multi-output device in your audio MIDI setup utility to be able to both hear and record the internal audio at the same time.

to set up a multi-output device:

Open Audio MIDI Setup: (found in /Applications/Utilities)

hit the '+' button in the bottom left corner and select "Create Multi Output Device"

then in the panel that appears on the right, in the Multi-Output Device tab, select "Built-in Output" AND "BlackHole 2ch". (and, if you want, any of your other connected devices.)

once you do that, (and BEFORE recording) you can choose "BlackHole 2ch" or "Multi-Output Device" in your menubar "sound options". 

to both hear the speakers and record the audio at the same time, choose "Multi-Output Device". before choosing multi-out, set the internal speakers' volume to a comfortable level first. you cannot control the volume once you are in multi-out mode.

it's working as expected on mu monterey system. if you are running into issues, you may have some conflicting software installed.

i'm thinking you should download and run the free version of EtreCheck so we can see if you have some software installed that is causing your issue. make sure you give "full disk access" to etrecheck. read how to use it by reading Using EtreCheck. if you need help interpreting the report, you can see how to post the report here by reading How to use the Add Text Feature When Posting Large Amounts of Text, i.e. an Etrecheck Report. and it automatically obscures sensitive things (like serial numbers) so you don't have to worry about sharing the report here.

I guess you need to route the audio through a third party app like Loopback and pick the routed audio as a source in QuickTime.

There's a free alternative named BlackHole. You have to check if it's compatible with Monterey.

i should think so. according to the developer's site it says it's compatible with OS X mavericks through macOS big sur. and even though it's not yet listed, it's chugging along fine on monterey. can you describe what is or isn't happening when you try to use it?

Personally I use Loopback.

I reported the GitHub post for akindword4u because he asked about Monterey compatibility.

understood.

you're welcome. i'm happy to hear you got it going. thanks for the update. :)
