HD Audio not playing through Plex



Hi, I've got my PC installed with PMS and PMP. I output via HDMI from my Nvidia video card to my Onkyo amp. When I play Blu-ray video in Plex, it does not play the HD audio. If I open the file in Windows and play it from the folder, HD audio comes through. Please can someone help me get HD audio to play from Plex? It just plays DTS 5.1.


I should mention that I don't have the audio tab in my settings page. I don't understand why.
This post should be under rasplex. sorry


Problem fixed.
