Is DVI capable of audio?
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.
Can you go from HDMI to DVI?
HDMI to DVI
As mentioned in the description of the DVI to HDMI device, DVI and HDMI use the same digital video format for the video. This means that if you are only using the video signal you can simply use an HDMI to DVI plug adapter or cable that simply changes the physical connections.
What is HDMI to DVI adapter used for?
For example, if a cable box or PC has DVI out, but the TV or monitor only has HDMI in, a DVI-to-HDMI adapter cable is used to connect the video. The audio must be cabled separately as DVI transfers only video. The HDMI circuit detects the DVI signals and switches to the DVI protocol.
