bondfreak 14 Posted September 5, 2017 Share Posted September 5, 2017 (edited) Hi guys, I discovered a strange behavior of my audio playback when a movie is paused. My AppleTV is connected to an Onkyo Receiver via HDMI and passes the audio signal to it (I would assume it is Dolby Digital because the ATV only supports this by default). Everything is working fine so far. Now I pause playback, wait for about 2 seconds or more and click on play. What happens is that Dolby Digital playback will be disabled (I can confirm that by looking at the receivers playback settings) and all audio is then only coming from the front right speaker. This is completely reproducible for all my files and I can fix it by going back or forth in the timeline. The audio will then "recalibrate" and playback is fine again. I am not sure if this problem is related to the AppleTV or my receiver, but I assume it is the ATV since no other apps show similar behavior. Is that something you guys know of or have a workaround for? EDIT: My server runs on Ubuntu 16.04 LTS.

ebr 14862 Posted September 5, 2017 Share Posted September 5, 2017 Hi. I've never heard of this one before. What is the audio setting on the Apple TV device (in the Apple menus)? Link to comment Share on other sites More sharing options...
bondfreak 14 Posted September 5, 2017 Author Share Posted September 5, 2017 Hi. I've never heard of this one before. What is the audio setting on the Apple TV device (in the Apple menus)? It's set to Dolby Digital 5.1. Link to comment Share on other sites More sharing options...
Gronda 1 Posted September 8, 2017 Share Posted September 8, 2017 I'm having the same problem. I think it's just those files that are being transcoded due to their DTS soundtracks but hadn't realised it was just the right speaker as my amp indicates left and right only. But after applying my ear to both speakers it does seem to be just the right that is putting out audio. Link to comment Share on other sites More sharing options...
corey 312 Posted September 9, 2017 Share Posted September 9, 2017 The Apple TV supports Dolby Digital tracks though so I wouldn't think transcoding would be playing a part in this. Link to comment Share on other sites More sharing options...
Gronda 1 Posted September 11, 2017 Share Posted September 11, 2017 Well, that's the only common factor I can identify thus far - mp4 files with a DD track work fine, those with a DTS track show in the dashboard as having some transcoding and also have this problem. I'll see if I can upload a log file tonight / tomorrow. Link to comment Share on other sites More sharing options...
ebr 14862 Posted September 11, 2017 Share Posted September 11, 2017 Could be an issue with the ffmpeg conversion from DTS to DD. Perhaps try a different version of ffmpeg...? Link to comment Share on other sites More sharing options...
