ATI Sound Card?

I've heard that ATI cards have Dolby True HD and DTS HD support. Does that mean I don't need a sound card or is that just a channel so that I could feed it through the HDMI?
 
That does indeed mean you don't need an additional sound card.

They're essentially soundcards themselves if you use the HDMI audio.
 
Can Nvidia cards do that? I looked on their website and it said something about that on Purevideo HD but that's not free...

I believe so but you need to connect the card to sound source through a small cable (SPDIF) I believe. Someone else will be able to confirm.
 
Basically ATI do this side better than Nvidia.
That's all there is to it, neither side are perfect, BUT if you have a AVR/HDMI sound setup, then ATI are better.
The trick behind it (now that DX10 audio has apparently been sorted), is either having your AVR on before the PC, or tricking the PC to output to it as a cloned screen and then turn that into a profile so you load the profile after havign switched the AVR on.

Sounds complicated but its actually very easy in practice :)
As the below video shows you can indeed use it as a sound card, which is great if you have a high quality AVR setup and a good screen.


It was good enough I dumped an X-Fi Fatal1ty which cost quite a bit, as I just didnt need it anymore. Most systems have onboard with mic input so the loss of the X-Fi mic input was not an issue.


PS. It's only the 5 series ATI cards which support HD audio over HDMI, the 4 series are limited to DD/DTS/PCM.

nVidia cards can pass an audio stream over HDMI, however it's not acting as a separate soundcard.

It has to use the motherboard's sound to do it.
 
It's got to be HDMI->HDMI using the official ATI HDMI dongle or a HDMI output built directly onto the card, due to differing pin-outs from standard DVI :)

I quite liked the feature, which is one of the reasons I'd be happy to move to ATIs new mobile cards, to get the feature back :)
