I just got my new Arc and Dolby Atmos sounds amazing, but I noticed that all other Dolby formats show up as “PCM 5.1” when using my Apple TV 4K. Switching the formatting back to Dolby solves this issue, but means I’m having to constantly tinker with the Settings to get the right Dolby surround for the right movie/TV Show. Has anyone else had this issue and is there a better solution? Is Apple aware of this issue? (Everything, including my Apple TV app on the Sony TV works flawlessly in switching formats, so this is an Apple TV 4K issue only.)
