Beta 2 Audio Passthrough

Any idea why under audio passthrough there is no selection for Dolby True HD ? I thought there was one in Jarvis ? When I play a dolby HD file my RCVR says PCM. I can play a DTS encoded file and the RCVR indicates its DTS.

I am using WASAPI… and a Emotiva XMC 1 RCVR…

Can someone look in audio passthrough settings and tell me if they have option to select dolby true HD …etc
