recording video sound from desktop does not work

Hey Tgwhe,

QuickTime Player will not natively record the screen of your Mac audio, just the external mic. There are third-party apps you can use to record the audio of your screen and some even work with QuickTime Player. You can read more about this here:

Record audio in QuickTime Player on Mac

Kind regards.

Hey there Tgwhe,

Thanks for reaching out to Apple Support Communities. We understand you’d like to know how to record video and sound on your Mac. We’ll be happy to help with this.

You should be able to do this with QuickTime Player on your Mac. You can read how to do this here:

Record your screen in QuickTime Player on Mac

Take care.

Hey there Tgwhe,

This is expected behavior in QuickTime Player and if you like, you can always leave feedback about this using the following link:
