Hey all,
My parents have a home theater with a Yamaha 5.1 receiver (RX-V477) and a 1080p Mitsubishi projector (VLT-HC3800LP). They currently have a Roku box hooked up to it that's starting to show its age so I got them the current-gen Apple TV 4K. However, no audio comes out at all from the Apple TV, whether it's steaming, sound effects (e.g., the clicking sound), or AirPlaying music to the Apple TV. To add to the mystery, for some reason when I select the S-Video input on the projector instead of the HDMI input, audio does come through the surround sound system– although with no video, since there's nothing plugged in on the S-Video input. Here's a simple diagram of how it's hooked up, pretty straightforward.
Apple TV <---(HDMI)---> Receiver <---(HDMI)---> Projector
I tried with my previous-gen Apple TV to troubleshoot, and I'm getting the same issue– video only, no sound. Plugging the Roku back in gives me both audio and video with no issues, all using the same HDMI cable. Here are some other things I've tried to troubleshoot, to no avail:
* Changing audio format from Automatic to 16-bit on the Apple TV
* Changing audio mode from Automatic to either 5.1 or Stereo on the Apple TV
* Changing video from RGB High to RGB Low (who knows, throwing a Hail Mary)
* Factory resetting the Apple TV, receiver, and projector
The Apple TV and HDMI cable are sending out audio, as evidenced by the fact that changing the input on the projector from HDMI to S-Video results in audio coming through. So what's going on?
