optical audio out

i have an optical audio out on my flatscreen tv to hear sound on home theatre system. Some files will not play audio out of optical audio… any reason? some files are fine, some are not…

thanks

Do you have Infuse set to Auto, or something else?

We recommend keeping Infuse set to Auto, and a bit more info on these options can be found here. https://support.firecore.com/hc/en-us/articles/217735707-Audio-Options-tvOS-

hi james, it’s set to auto.

only some files dont pass thru the optical audio… encoding maybe?

With Infuse set to Auto, the actual output will be determined by the Surround Sound option found in the main Apple TV Settings > Audio & Video.

You may try adjusting this option to see if it helps with your particular setup.

Well other shows work so I’m guessing it’s not that otherwise no shows at all would work.
