I have my 4K Apple TV connected to my Lg tv the from the optical out from my tv to my Yamaha surround sound receiver. I seem to only get a stereo signal from the amp. It doesn’t matter what apps or sources I’m using on the Apple TV. The older Apple TV with an optical connection directly to my amp worked fine. My receiver has no HDMI inputs. Any help would be appreciated
Apple TV 4K, tvOS 14
To facilitate surround sound with the described setup, you may need to change the Apple TV Settings for Audio Format to Dolby Digital 5.1. (The default Auto setting will output PCM Multichannel if possible over HDMI, which is not compatible with optical passthrough.)

I probably wasn’t too clear. The above settings worked but I had to select 16 bit for the audio mode in addition to selecting 5.1 audio for audio format. It works fine now with both those settings selected.
Hi. Thanks for the info. I had to change the "audio format" to 5.1 as you suggested but I also had to select the 16 bit for "audio mode". It didn't seem to work otherwise.
What are your tvOS audio settings? -> in the tvOS Settings app under: Video and Audio/Audio Format
No surround sound from amp
