My setup:

• Soundbar: Samsung Q700C - it supports TRUEHD/DTS-HD
• App version: Emby for Samsung 2.3.3
• Server Version: 4.9.3

Issue description: Emby App for Samsung Transcode TRUEHD 7.1/DTS-HD MA 7.1 into AC3 384 kbps

I attached server logs for two movies(Avatar 2 is TRUEHD 7.1, Hidden.Figures is DTS-HD MA 7.1), also their mediainfo

Samsung TVs do not passthrough audio formats such as TrueHD or DTS.  

Look for the table similar to the one in the link below in your user manual.

https://developer.samsung.com/smarttv/develop/specifications/media-specifications/2022-tv-video-specifications.html

Any audio codec not in that list has to be transcoded by Emby or the file will not play.

You can test this out by turning off allow audio transcoding in your user playback settings on Emby server.  Turning that off will force Emby to passthrough all audio formats.

The solutions are:

• allow the server to transcode any unsupported audio
• select a supported audio format before clicking play.  Most UHD discs come with an alternate AC3 track at 640kbps
• hook up an external box such as nVidia Shield which supports TrueHD, DTS, etc to the input port of your soundbar and use the Emby client app for that device instead.
