Hey guys this is my setup. Please explain to me how to enable full lossless audio through hdmi

Gtx 580 (question? Is my audio coming from the graphics card?)
I7 970
6gb

New onkyo tx-nr709 with full hdmi support. I'm using full hdmi 1.4 cables. Two to be exact. One from the gtx 580 using the hdmi mini out adapter to the reciever and the other from reciever to lg 3d led tv.

I don't know what to select in the menus. Can someone please help me get this going.

Hi,

as far as I know the GTX 580 does not support lossless bitstream for HD Audio formats like DD-TrueHD and DTS-HD-MA

Ok thanks Michael. Now that that's out of the way. I just picked up a gt430. And it says it does bitstreaming. Hd formats. Question is... Looking at the powerdvd info bar it shows audio output. It still shows compressed data. Is it supposed to show uncompressed. Though now my onkyo says dts hd mstr audio.

Because it is bit streaming it is showing compressed data but after it get over it will automatically will become uncompressed or else you can do it manually !! Love Cyber-Link !!

Hi,

the HD audio formats DTS-HD-MA and Dolby-TrueHD are lossless compressed

Hello Friends

Greetings! This is my first time setting up HTPC. Here is my issue.
I have 2600K Sandy bridge with NVIDIA® GeForce® GTS 450 Graphics card. I have PowerDVD 9.
I believe I have all up to date drivers. I was playing "My Bloody Valentine" Blu-Ray disk with DTS-MA audio. And it won't show on my Onkyo HT-S7300 receiver. I was able to select HDMI pass through in PowerDVD 9 setting with Compressed audio. But on my receiver it only shows DTS. And it only plays 5.1 audio. Where as the blu-ray has DTS-MA 7.1. I am unable to understand even though my HTPC is passing compressed audio in Bit Stream to my receiver through HDMI, why is it downgrading the audio from DTS-MA 7.1 to DTS 5.1.

The display on PowerDVD screen does show that input audio is DTS-MA 7.1 and output audio is Compressed Audio.

If I play same Blu-ray on my Samsung BD-6900 Blu-Ray player with same Onkyo receiver, I get full 7.1 Audio with DTS MA displayed on my receiver.

Can some one help me out here? What should I do to get DTS-MA on my HTPC?

Any help will be highly appreciated.

ALSO, how do I test that it works for Dolby-TrueHD? Is there any website where I can download some files to test Dolby-TrueHD audio?

Thanks
