Does DVI carry audio signals as well as video?

By Asher Moses on 05 September 2006

The reason you're not getting any sound is because the DVI connection doesn't transfer audio, just video.

HDMI transfers video at the same quality levels as DVI, but the added advantage of HDMI is that it also carries sound through the one cable. Since the output on your HP mediacentre is DVI, you'll need to also connect an audio cable (the red/white or left/right stereo kind).

    I needed to connect a Dell Laptop to a TV with HDMI via UTP data cables for extra range, (15m).
    It had what I assumed was HDMI output but turnbed out to be proprietry Video socket as well as DVI.
    I thought I was going to need seperate audio but when I connected it using a DVI to HDMI adpater (DickSmith) I was surprised to find that the adio was present. I too thought DVI was Video only, but it must support Audio as well.

    hoej, the cord your using is hdmi to dvi-d.
    dvi-d is a larger pinset than dvi. it supports audio.
    i just recently bout a 30 god damn dollar cable so i could display my xbox to my monitor.
    the picture is more than exceptional, but i'm using standard dvi, so no audio.

    i need audio breakout jacks installed on my xbox. i'm very tech savvy and could do this myself, but havent the slightest idea where to start.

    anyone know of a good tutorial for this?

    that's because the DVI-HDMI can only support video (the DVI side doesn't have audio capacity). in order to support both video and audio, you would need HDMI capability on both ends.

    I have an xBox 360. (as you can tell by my username) the DVI I have is an HDMI on the other end, plugged into my xbox. the DVI is plugged into my DELL monitor. First, I cant get sound any way I try. And second, I am baffled by the fact that HDMI supports audio and still wont play any audio at all.

    Please help... xboxgeek951

    My Asus P5N7A-VM is connected from DVI to HDMI by standard DVI-HDMI-cable. Surprisingly I am getting full sound on my television (with no separate audio cable).
    I think this is only supported by newer motherboards.

    Some new video cards have audio output through DVI connector but you have to use the supplied DVI to HDMI adaptor to get the sound.
