I'm confused, and would appreciate someone clearing this up for me. I run Frodo 12.2 on Vista 32bit, using a Nvdia GT620 to an Onkyo 509 AVR. Following the guides here, if I look at the properties of this connection as the playback device, the only supported formats I see for the Nvidia High Definition Audio are Dolby Digital (even tho both the video card and AVR support DTA-MS, TrueHD, etc). "DTS" and "Microsoft WMA Pro Audio" are listed, but don't work; Windows says it was unable to play the test tone, and so these 2 are unchecked.
I tried an EDID overide, created by MonInfo - no other formats show. I have the latest drivers (320.49, updated today). I also don't see a max number of channels, like the guide screenshots show, but that may just be a different between ATI and Nvidia.
Yet, in XBMC, when I set the audio to use WASAPI for both audio out and audio passthrough (with HDMI and 5.1 set), I can play test files encoded with DTS-MA and TrueHd. They work perfectly, no choppiness on either audio or video. The AVR even shows "DTS-HD MSTR" and "TrueHD" on it's console. (these are sample files HD audio files I downloaded)
Yet the guides here say "If formats are missing from this Supported Formats tab then they will not playback in XBMC, this must be fixed at the OS level first.". So how come mine do play, and play correctly, even though they aren't fixed at the OS level?
The other weird part? These files do *not* play correctly at the OS level (exactly as the guide implies). Using the latest VLC, and the latest CCCP codecs, these files do not trigger the "DTS-HD MSTR" and "TRUEHD" indicators on the AVR console. Oh, they play, but they don't trigger the AVR they way they do when I play them with XBMC.
So what am I misunderstanding? The behavior at the OS level seems consistent with the guides, but not when played through XBMC. What have I missed?
Thanks
