570 GTX passthrough HD audio tracks to my receiver? or will it downsample?

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

For some odd reason the higher end nVidia GPUs don't support the passthrough of HD audio.
The GTX570, 580 and 590 don't support it.

The cheapest way to play a movie would be to buy a GT520 and have the tv playing through that (if your motherboard has the space)

Supports high-definition 24-bit, 96 and 192 KHz multi-channel audio sampling rate support for compatible Blu-ray movies

hmmm! well I need to buy a headphone amp for my new headphones, so might as well get a decent sound card that does the LPCM to my receiver and has a headphone AMP on it

Is there such a card that does both LPCM and has a headphone AMP, from past thinking am sure they either did one or the other

Anyone?

Probably best to ask in the sound section if you're interested in a sound card.

It won't be a cheap one is there is

Might just trade my GTX 570 for a ATI card with the same amount of spec, that does LPCM
