ThankAIThe Mac Relay.
A lightweight menu-bar helper that lets AirAudio play through your TV's speakers via an Apple TV, and keeps an Apple TV in sync when it's part of a group. It's optional — HomePods, AirPlay speakers and Google Cast speakers don't need it — and you set it up once. New to AirAudio? Start with the HomePod guide.
New to AirAudio? Start on Android first — get the app, then add the relay if you want sound from your TV's own speakers.
Unsigned Apple-silicon ZIP — verify the published SHA-256 before opening it.
Only for Apple TV.
Use the relay for
- TV speakers — playing your phone's audio through the TV an Apple TV is connected to
- Apple TV in a group — the best sync when an Apple TV plays alongside other speakers
You don't need it for
- HomePods, AirPlay and AirPlay 2 speakers, Macs and Google Cast speakers — AirAudio reaches them directly
- Day-to-day streaming where the relay isn't requested
AirAudio tells you in-app exactly when an output needs the relay — so you'll never wonder.
Three steps, once.
Download & open
Grab the relay on a Mac that's on the same Wi-Fi as your phone, then open the downloaded file.
Drag to Applications
Move it to your Applications folder and launch it. It lives quietly in the menu bar — no window to manage.
Pick it in AirAudio
On your phone, choose your Apple TV. The relay forwards the audio to the TV's speakers automatically.

Requirements
If something's off.
AirAudio doesn't see the relay
Make sure the Mac and your phone are on the same Wi-Fi network, the relay is running (look for its menu-bar icon), and your firewall isn't blocking local connections. Relaunching the relay usually re-announces it on the network.
macOS won't open the download
If macOS warns about an app from outside the App Store, open System Settings → Privacy & Security and choose Open Anyway for the relay. You only need to do this the first time.
Do I need to keep the Mac on?
Yes — the relay forwards audio while you stream to your Apple TV, so the Mac needs to be awake and running the relay during playback. It uses almost no resources when idle.
Is the relay required at all?
No. It's optional and only needed for TV-speaker output through an Apple TV. HomePods, AirPlay speakers and Google Cast speakers get the audio directly from your phone.
