No audio from an Apple TV 4K through an AV receiver is almost always the input assignment, a format the receiver can't decode, or the connection layout — not a dead receiver. How the Apple TV reaches the receiver decides which fix applies, so start there.
Which layout do you have?
- Apple TV → receiver (HDMI in) → TV: the receiver decodes audio directly. Best and simplest — most "no sound" here is the input assignment or format.
- Apple TV → TV → receiver over eARC: audio returns to the receiver over the TV's eARC. More links to fail — needs eARC and CEC working.
Fix it (Apple TV plugged into the receiver)
- Select and assign the right input. Choose the receiver input the Apple TV is on, and confirm that input's HDMI/audio assignment points at the correct HDMI jack (Setup > Inputs > Assignments). A mismatched assignment is the #1 silent cause.
- Set the Apple TV audio to a format the receiver decodes. Settings > Video and Audio > Audio Format > leave on default (Auto); if it's forced to Dolby Atmos and the receiver can't do it, you get silence. Set Change Format off to test.
- Check the receiver's audio mode isn't muted or on a "pure direct/analog" mode that bypasses HDMI audio.
- Use a certified cable Apple TV → receiver — a marginal one drops the audio handshake while video works. A handshake that keeps dropping rather than staying silent is covered in Apple TV receiver HDMI handshake fixes.
Fix it (Apple TV through the TV's eARC)
- Confirm eARC + CEC. The TV's eARC port to the receiver's eARC, with eARC enabled and CEC on at both ends, and the TV's audio output set to the receiver.
- Set the TV's digital audio to Bitstream/Auto so it passes the Apple TV's audio to the receiver.
- ARC can't carry Atmos — if you want Atmos this way, it must be eARC.
Power-cycle and isolate
- Power-cycle in order: Apple TV, receiver, TV unplugged 30+ seconds; receiver first, then TV, then Apple TV.
- Isolate the format: set the Apple TV to stereo/PCM — if sound returns, it was a surround format the receiver couldn't decode.
FAQ
Apple TV plays but the receiver is silent. Check the input's HDMI assignment and set the Apple TV audio format to Auto/PCM. A format the receiver can't decode plays silent.
Best way to connect Apple TV to a receiver? Apple TV → receiver → TV. Audio decodes at the receiver with no eARC return to fail.
No sound through the TV's eARC path. Enable eARC + CEC at both ends, set the TV's audio output to the receiver, and set the TV's digital audio to Bitstream/Auto. The full sequence is in the eARC no sound with receiver checklist.
It works in stereo but not surround. The receiver can't decode the format the Apple TV is sending. Set Audio Format to Auto, and for Atmos use eARC (not ARC) or plug the Apple TV straight into the receiver.
