I can’t get the Apple tv to play in Dolby surround . It defaults to 2.1 stereo. My Shield Tv and Fire Tv will play in Dolby surround without issue. All three have the same hdmi cable type and everything has current updates. When i check settings it says stereo. I can attempt to force Dolby but it still plays in stereo only?
Sorry should be in hardware not app.
Apple TV 4K has 4 audio formats available:
Apple TV should have the Audio Format setting set to ‘Auto’ (PCM Multichannel), when connected to a great receiver like yours. Apple TV is designed to default decompress Dolby Digital/Dolby Digital Plus to PCM 5.1/7.1. There is no passthrough option for Apple TV. You will not see a DD logo light up on the audio system.
PCM does not denote Stereo.
(‘Dolby Surround’ is an ambiguous term, and has seen a 2014 re-definition.)
What sources cause this Dolby Surround to 2.1 conversion? Does this happen for any particular app or service?
It stays in stereo no mater what app (source) I use. I am wondering if a factory reset might help.
Apple tv 4k 2nd gen with Denon avr-s970.
