A TV mounted on a wall with a speaker icon being crossed out.

If you run into the issue where your Apple TV remote stops controlling the volume, restart the remote itself. I have completely taken apart my media setup trying to diagnose this weird intermittent issue. Don't be like me.

Fix the issue by holding the 🖥️ + volume down buttons for five seconds. You should see the light on your Apple TV blink off and back on. Wait for the remote to reestablish its connection to the Apple TV; with any luck, you should be happily controlling the volume again.
