Hi, i’m using kodi with the official plex app.
Case 1: Computer with ubuntu 18.04, connected via HDMI to an 5.1 system.
Case 2: vero 4k+ with HDMI to the same system.
In both cases there is 5.1 sound, if i use kodi with local media files. Case 2 works even with passthrough.
The offical plex app for kodi works only with 2.0 audio (case 1&2). I tried all settings, nothing worked.
Fun fact: i tried plexkodiconnect, there is 5.1 sound available (but also no passthrough).
The plex Server is from a friend (remote over Internet). Transcoding is activated (1080p, 12 MBits).
You’re certain you checked the audio settings in KODI (not just in Plex)? Turn on “Expert” options, set your system to 5.1, and enable passthrough for the formats your system can natively decode.
