Windows 7: Getting sound through DVI - HDMI

DVI-A is analog video only, DVI-D is digital video only, and DVI-I is integrated (digital and analog Video). Dual link is used to support large displays with high resolutions. There is no audio signal on a DVI connector. You can convert it to HDMI but it still won't have any audio on it. You need a video card with an HDMI output. Or feed the audio output from your sound card to the audio in on the back of the monitor or TV. The sound driver for the HDMI on the Video card is installed with the Video card drivers. It will be ATI/AMD or Nvidia, not Realtek. Realtek would be for your motherboards onboard sound card.

The Realtek drivers is ATI Realtek High Defintion Driver.

And yes you do get audio from DVI to HDMI - check ATI website especially the 3xxx series onwards, as the card already has HDMI on, it has audio chipset, and this is passed through the DVI-d also, and if a dvi-d to hdmi cable or convertor is used you can get sound.

Some of the ATI 2xxx cards also, and the x1950 pro gtx

Ok if the card has a HDMI port on it why are you doing the DVI to HDMI. Sorry that just doesn't make any sense. Use the HDMI port.

Could you provide a link to this information? Does your card do this? Is it a special ATI DVI to HDMI converter that's used. I've looked at the DVI specs and pin out and see no mention of sound, only Video?

My question is how do i enable the sound through my x1950 pro
You don't as the x1950 doesn't have any audio capabilities at all. You want audio over DVI/HDMI you need at least an HD 2xxx series or higher, and then the audio over only works with the adapter that comes with the card (on the cards that didn't have a native HDMI port).

In control panel i have the usual ac97 and a unknown game adaptor, now im assuming that the unknown gaming adaptor is the sound section of my card
Nope, that would be for the gameport on the motherboard,

which you can ignore as gameports are no longer supported under Windows 7. You might be able to get the last XP (or Vista if available) driver to install if using 32 bit Windows.

Actually, on the ati cards that support audio on the dvi port, you don't need the dongle if you have a dvi to hdmi cable. All the dongle is doing is giving you an hdmi port.
My old hd3650 had 2 dvi ports, white and yellow. The yellow port had the audio pins and I just used a dvi to hdmi cable on the yellow port to run to my HDTV for video and sound.

This is the card I had,

That`s the point, does his card carry audio ?

Look at the pinout on the dvi port you are trying to use and look at the pinout on the DVI to HDMI cable you are using. Do they both support video AND AUDIO ?

As I said above, no it doesn't. No ATI/AMD card before the HD 2xxx series has audio. I used to have (and still do in my kids computer), and it has zero audio capabilities.
