tedfroop 33 Posted September 2, 2023 Share Posted September 2, 2023 No solution needed - just an explanation please as I can't find one..... What the heck is the difference between DTS-MA Codec ID A_DTS and DTS-MA Codec mp4a-A9, Emby can understand and transcode either, and my AVR chokes on A_DTS but plays mp4a-A9 no problem. Again - it's a curious mind wants to know thing...... Link to comment Share on other sites More sharing options...
Luke 37070 Posted September 2, 2023 Share Posted September 2, 2023 Hi, we exactly happens with your avr? Have you tested multiple files to isolate this as a pattern? If it’s just one video it could be something else about it. anyway the latter could be dts-x but I’m not positive. Link to comment Share on other sites More sharing options...
tedfroop 33 Posted September 3, 2023 Author Share Posted September 3, 2023 Nothing happens on my AVR with A_DTS. It continues as if its playing but there is no sound. If I ask to correct playback it falls back to remuxing to Dolby 5.1. My AVR is a older Yamaha RX V567, which is connected Arc/Earc to my TV for audio only as it can't handle 4K at all, but plays DTS-MA 7.1 and Dolby TrueHD 7.1 no problem. Is A_DTS a newer codec? that would say why its not recognized. What happened was I ripped two files that both showed mp4a-A9 as the Codec. Both files played as expected, DTS-MA tracks and video. Joined the two files with MKVToolnix and thats where the codec changed to A_DTS, which played only with remuxed audio. I joined the files later with Shutter Encoder and the joined file showed the mp4a-A9 codec which played no problem - sound and video. 1 Link to comment Share on other sites More sharing options...
