Apple TV: No sound when mirroring MacBook Pro

abthesp,

Which app are you using? Depending, you might find a speaker or AirPlay icon that will let you select the TV as your audio output device. Here's an example: Use AirPlay to stream audio

"Stream audio from your Mac

1. Make sure that your Mac and speaker are on the same Wi-Fi or Ethernet network.
2. Open Apple Music on your Mac.
3. To the right of the volume slider in Apple Music, click AirPlay .
4. Click each speaker or TV that you want to play the current audio to.

If you don't see the AirPlay icon  or if you want to stream audio from a different app:

1. On your Mac, select Control Center  in the menu bar. 
2. Click AirPlay  under Sound. 
3. Select a speaker that you want to play the current audio to.

You can't use AirPlay to stream audio to multiple speakers from the menu bar on a Mac."

Best wishes.

Hi abthesp,

​Thank you for using the Apple Support Communities. We see you have video but no audio when using AirPlay on your Mac, but you do have sound with your iPhone. We'd like to help out. This resource might be a good starting point If screen mirroring or streaming isn't working on your AirPlay-compatible device:

"If you see video but don't hear audio

If you don't hear audio when streaming video from your iOS device or Mac to your Apple TV, make sure that the volume is turned up and not muted on both your iOS device and your television or receiver."

In addition to checking the volume on the Mac and television, you might want to check within the app you're using to see if there are in-app volume controls. If that doesn't help, try restarting the Mac by clicking Apple menu () > Restart and see if that helps.

Let us know. Take care.

abthesp,

Glad to hear that worked!

Have a good one.
