Windows 10, no DTS Audio
i have been using plex for quite a while locally on the server. i recently had a requirement (baby like bright button!) to move the server out of the Home Theater and into an audio Rack (out of sight). when i did this i went out and bought a refurbished Lenovo M92 pc (super tiny and doesn't use much power) and did a clean install of Windows 10 (don't want bloat!).
Whenever i play a video that is DTS encoded i don't get any audio without triggering the transcoding. Any other video file i play works without issue (direct play\stream). when i play the same problematic video through VLC or the Plex web client it plays the DTS audio no problem, so i dont think it is the DisplayPort 1.2 to HDMI active converter i have inline to my Denon Receiver (supports DTS Audio , DTS-HD, True HD, Dolby Plus etc.).
I have updated every Intel chipset driver\firmware i can find and scoured the google for helpful results (the RealTek chipset is only used for the analog ports). cant find anything. any ideas?? this is obnoxious!
