DVI ports do not support audio. DVI is a video-only standard, so you will always need a separate audio connection — unless you use a DVI-to-HDMI cable with a graphics card that supports HDMI audio output.
- You use a DVI-to-HDMI cable and your GPU supports HDMI audio via DVI
- You run a separate 3.5mm or optical audio cable alongside the DVI cable
- You use a standard DVI cable alone — no audio regardless of connector type
- Your graphics card is older and does not support HDMI audio over DVI
- You use a passive DVI-to-HDMI adapter without GPU audio support
Why DVI Has No Audio
DVI was developed by VESA (Video Electronics Standards Association) as a pure digital video interface. The specification never included audio signal pins, so no version of DVI — DVI-D, DVI-I, or DVI-A — can carry sound through a standard DVI cable.
This is different from HDMI or DisplayPort, both of which were designed from the start to carry audio and video together. If you need audio and video in a single cable, DVI is simply the wrong port for the job.
The One Exception: DVI-to-HDMI with GPU Support
Some modern graphics cards can output HDMI audio through their DVI connector. In this case, using a DVI-to-HDMI cable — not just a passive adapter — can deliver both video and audio to an HDMI-equipped monitor or TV.
This only works when the GPU driver specifically enables HDMI audio over the DVI output. If your card supports it, you may need to select the correct audio playback device in your operating system’s sound settings. If your card does not support this feature, no cable or adapter will add audio to a DVI connection.

Quick Setup Comparison
| Setup | Works? | Need | Note |
|---|---|---|---|
| DVI cable only | No | Separate audio cable | Video only, always |
| DVI-to-HDMI + supported GPU | Yes | DVI-to-HDMI cable | Check GPU specs first |
| DVI + 3.5mm audio cable | Yes | 3.5mm cable | Most reliable workaround |
| Passive DVI-to-HDMI adapter | No | GPU audio support required | Adapter alone is not enough |
Best Workaround: Use a Separate Audio Cable
The simplest and most reliable fix is to connect a 3.5mm audio cable from your computer’s headphone or line-out jack to your monitor’s audio input or to external speakers. This works regardless of your GPU model or driver version.
Alternatively, if your setup allows it, switching to an HDMI or DisplayPort connection eliminates the problem entirely since both standards carry audio natively. For more on single-cable video solutions, check out whether USB-C supports video as a modern alternative.
Bottom line: DVI port audio is not supported by the DVI standard itself. For most users, running a separate 3.5mm audio cable is the easiest fix. If your GPU supports HDMI audio over DVI, a DVI-to-HDMI cable is a cleaner solution — but verify your card supports it before buying.
