Recording screen on macbook

there is no sound in the video, even though it was playing on my headphones?

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.

Hello firdavs192,

You are asking about screen recording on your Mac and specifically why the audio didn't record while you were using headphones. Your Mac microphone will need to be able to capture the audio coming through, which may not with headphones versus the onboard speaker. Look at guidance here: How to record the screen on your Mac - Apple Support

To record your voice or other audio with the screen recording, choose a microphone. To monitor that audio during recording, adjust the volume slider. If you get audio feedback, lower the volume or use headphones with a microphone.

Try a screen recording without headphones connected to see if the audio gets captured.

Best regards.
