I'd like to hook a PC to my HDTV, and it'd save a lot of hassle if the HDMI could also carry the sound as well.

I'm referring to the highend gaming cards like GTX280/260 and future ones.

The GTX series have SPDIF inputs on the cards with little wires that you can connect to your sound card internally. This should pass any digital audio through to your HDMI.

Yes my $29.00 ASUS ATI 3450 HDMI (http://www.newegg.com/Product/Product.aspx?Item=N82E16814121259) does great, Blu-Ray and HD-DVD. OOh $19.99 after mail in rebate.

Yea there are ATi cards going back to the x1650 pro that have the ability connect like CaptNKill stated. I believe you can do that as well on some of the older midrange Nvidia cards that have an HDMI port.

Hmm, that actually brings up a question. Since the GTX have dual DVI, where does it pass the audio through on a DVI connector? There must be some pins set aside for audio using the adapter...

EDIT: I'm looking at the pinouts and I'm not really sure where it would be located at. I've always been under the impression that if you wanted to get audio as well it has to come from an HDMI port directly on the card. If you used the adapter it wouldn't have the right stuff to do it. A DVI-DL has more pins than an HDMI cable though, so I wonder if they are able to modify the port to pass audio. Where is our resident production manager to comment on this. :p

Specific adapters will allow audio to pass through on a GTX280. You can contact your video card distributor to order the DVI-HDMI dongle. They should also supply the SPDIF cord you can attach to your motherboard or sound card.

ATI 2900 38xx 48xx all have built in HDMI sound output without the need of a connector.

I have my X-Fi going into my GTX 280 which is connected to my 32" TV via HDMI. The sound is 100% clean and crisp.

So that realtek chip is actually on your video card?

That's crazy... all the time these cards have been out I've never heard of this.

Still, if you have decent onboard sound it shouldn't be a problem to pass it through the video card with a wire. Its digital so there shouldn't be any loss of quality.

No, my bad I didn't show the pull down in the audio properties it's a ATI HD audio from the HDMI. The realtek is the on board sound (optical to the Z680's).

Still, that's pretty nifty.

Does it do Dolby Digital Live or DTS connect or anything like that?

nah, also you need something from 46xx and up series (or nvidia 8200, 8300) to pass the new HD sound streams.

Feyy, out of those that you mentioned only HDMI Video+Audio is unique to ATI.

it is nice feature, that why I have 3450 in my HTPC now, will probably upgrade something like 46xx, since I need better audio support.
