That's weird. Plus is an extension of Dolby Digital. Supporting Plus SHOULD mean that it supports the base Dolby Digital, right? For giggles, in whatever device you are using to run the Jellyfin player, go to the Settings > Playback > Audio Settings > Maximum Allowed Audio Channels. Set it to stereo. I'm wondering if your HDMI dongle thing isn't downmixing correctly for or something so let's do the downmixing in software. Maybe this is a bug in the dongle's firmware?
