Does Aurora Realtek support Dolby Digital Live?
This is my first gaming pc, and I am planing to hook it up through spidf to my onkyo tx-sr607 receiver. I assumed that for games it would automatically send out a Dolby Digital signal, but after browsing the web I have learned that the Realtek would need to have Dolby Live to encode the signals from games. I am not sure what Realtek comes on the Alienware mobos (888s?), but on the Realtek site they list Dolby Live as optional which confuses me even more. Is it optional by way of software? Or is it optional for the mobo manufacturer to install the necessary hardware?
If someone could help me out here I would greatly appreciate it. My computer is currently being shipped to me, and if I need to get a sound-card with onboard Dolby live then I would prefer to pick it up so I can install first thing. Although I would prefer not to have to get a sound card because I have no free pci slots, requiring me to remove the network card I ordered, and I am a total noob when it comes to PCs so I am a bit nervous about having to do a switcheroo.

What video card did you get? If you got a 5870 you could output your audio and video to your onkyo reciever via hdmi. No need for a sound card.

I got the GTX 295, checked into it but it only does pass-through:( No Dolby live like the ATI.

Well, after doing exhastive research on the matter I have decided that buying a sound card is going to be the best way to go by far. I want EAX 5.0 and the on board sound can not provide this.
Does anyone know what sample rate video game sounds are compressed to? Are they 192khz 24bit? The only reason I ask is if the answer is yes I might splurdge on an HDMI audio card (like $250 though) for the higher quality 5-channel uncompressed PCM audio. I am assuming the sound is compressed though, possibly to Dolby D like sample rates (48khz).
