How to Transfer Audio Over DVI
If you want to transmit audio over DVI, you’ll need to use a special DVI-to-HDMI cable. Assuming your computer’s video card supports HDMI audio via DVI, this cable will allow you to transmit both video and audio using a single cable. The good news is that most modern video cards support this feature. If you have an older video card, however, you may have to upgrade it.
Unlike its DVI counterpart, the High-Definition Multimedia Interface (HDMI) supports both video and audio. HDMI uses EIA/CEA-861 standards to define formats, compression rates and auxiliary data. Technical jargon aside, it’s become the preferred interface because of its ability to transmit video and audio over a single cable.
A DVI-to-HDMI cable lives up to its namesake by taking DVI signals and transmitting them to an HDMI port. If the video card supports HDMI audio via DVI, however, it will transmit audio and video to the HDMI port. So, if you want to transmit audio over DVI, first check to see if this feature is supported by your computer’s video card (you may need to install the latest driver). If it’s supported, pick up a DVI-to-HDMI cable and connect your two devices.
Aside from a DVI-to-HDMI cable or similar adapter, you’ll have to use two cables to transmit audio and video when using DVI. For instance, you can use a traditional DVI cable to transmit video and an analog audio cable to transmit audio. Of course, HDMI is the ideal interface for video and audio transmission. Being that not all devices feature HDMI ports, however, a DVI-to-HDMI cable may be your best option.
A simple Google search will clear this up.
