I have a Dell Desktop with a DVI output I am not currently using. I would like to connect it to my new HD LCD TV (about 30 feet apart). As I understand it, the HDMI cable will carry video and audio. I read a lot here however that DVI does not include audio. So my question is how do I get the audio into the HDMI cable to send it to the TV? Are there audio pins in the DVI output connector and is there an adapter that puts them into the HDMI cable?
