No Audio Output from my Apple TV 3

Correct. My projector does not have the ability to output audio.

All I am able to do is play it off of my 2018 MacBook Pro, using a USB C adapter to HDMI. Sound comes out of the MacBook Pro.

The Projector is used as a second screen, I guess you’d say. I’m dragging the window over to it, maximizing it, and getting all of that output that way.

Typing out this reply, I just thought of something. What about using a little Bluetooth speaker: That would work as it’s own little device. I don’t have such a speaker, but that should fix it, being a little projector and a little speaker.

For Note:

Go Here: 10.14.5 Update --- Connected Devices are Getting Hot

The projector gets hot with that 10.14.5 update, as do all over connected devices. So, I downgraded it to 10.14.4, using the Time Machine Backup I created prior to the update.

I don’t have a clue as to what the reason for all that heat would be.

The speaker is Bluetooth; so, being that it is not hardwired, then heat should be of no issue.

Good to know. I plan to upgrade my Apple TV 3 to the 4th Version, then.

Thank for the help vazandrew.
