Plex Server on Synology NAS and also Windows recognized a DD+ Track as 5.1, but it is 7.1. Also playback on AppleTV or ios is 5.1. When using Infuse App it shows also the plex server information in the overview that it is 5.1, but when playback i get 7.1 channels. Also the player itself shows Dolby Digital Plus 7.1… When search in the forum, there was some discussion in 2019 and then it was fixed. This bug is open again ? ---

As I understand it Apple TV selects the format that is supported by your equipment. You might also verify your audio settings on Apple TV. I believe only the 4K version supports HD audio but could be wrong. ---
