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.
