How to get internal sound for screen recording on a MacBook Air M2 chip

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.

can you provide screenshots of;

your multi out settings in your MIDI settings?

your menubar sound options?

and your recording controls options?

that's your multi-out MIDI settings. it looks fine. but I still need to see your menubar sound options. please click on the speaker icon in the menubar and screenshot the dropdown menu. like this shown below.

ok. when you are getting to do a recording, please choose "multi output device". "red arrow from your screenshot:

and finally, can you open your recording options by using the keyboard shortcut "shift-command-5" and choose "options"

and please see which input (microphone section) that you are using.

sorry, my last post criss-crossed yours. I'm glad you got it working. :)

you're welcome. :)
