Hi I am just wondering that when playing a blueray movie on my HTPC with a 570 GTX installed, if it would passthrough the HD audio tracks to my AV receiver fo it to decode? or am I going to have to buy a expensive sound card do this?

Thanks

If you want to bitstream DTS-HD MA/True HD you'll need to buy a separate HDMI soundcard. The 570 does not bitstream (correct me if I'm wrong).

I feel your pain, I was pulling my hair out trying to get a straight answer on any of the Nvidia line up. I recently purchased the GTX 550 Ti and one of my requirements was lossless. If you go to the product page, you won't learn much but I did find this on the GTX 570: http://www.geforce.com/Active/en_US/...df/GTX-570.pdf

Go down to audio and you will see 24bit. There is also this link on my card: http://www.nvidia.com/object/product...-550ti-us.html and if you click features, you will find bitstreaming list towards the end.

What are you guys trying to say? No. The 570 definitely does not bitstream anything over DD+. No DTS-MA, No True-HD.

Another option is to use a media player like JRiver to decode and send as PCM over HDMI.
