DVI is short for Digital Visual Interface. It has been around for decades and is still present on many computers and monitors today. People often wonder about its audio capabilities. It is well known for video. But there is ongoing confusion about whether it also carries sound.
Some assume that since HDMI supports both, DVI might as well. However, the reality is a bit more nuanced and depends on the type of DVI connection you are using. Let’s break it down clearly so there is no uncertainty the next time you plug in your display.
What is DVI?
As mentioned before, the Digital Visual Interface is often called DVI. It was created to replace older analog connectors, such as VGA. Its main role is to send high-quality video from a computer or graphics card to a monitor or projector. Many things still rely on DVI ports, such as:
- Older PCs
- Gaming setups
- Professional equipment
A standard DVI cable computer can be found in offices, classrooms, and home setups. DVI still holds its ground even when HDMI has largely taken over for most devices. But the key question remains, and that is: Does DVI support audio in the same way HDMI does?
Different Types of DVI
DVI comes in several forms, and understanding the differences helps clarify the audio question. Some versions handle both digital and analog signals, while others stick to one. Here is a closer look at the main types.
DVI-I
DVI-I stands for “integrated.” It supports both analog and digital signals. This makes it versatile for connecting different displays. However, when it comes to sound, DVI-I is still video-only. So, does DVI support sound here? No, it does not. A separate connection is required if you need audio.
DVI-D
DVI-D stands for “digital.” It is one of the most common versions and is widely used for computer monitors. People often ask, Does DVI-D carry audio? The straightforward answer is no. DVI-D sound is nonexistent because the format was designed solely for digital video. This means you must run another cable for audio. You can also use an adapter with HDMI.
DVI-A
DVI-A stands for “analog.” It is less common and mostly outdated today. It carries analog video signals only, very similar to VGA. If you are wondering, does DVI-A carry sound, the result is the same. There is no audio function in this type either.
Does DVI Support Audio
Questions like Can DVI carry audio or Does DVI transfer sound often come up. The answer is always the same. DVI was created with the sole purpose of delivering video. DVI requires you to find another solution if you want sound. This makes it different from HDMI, which merges audio and video in one cable.
Whether it is DVI port audio, DVI port sound, the result is identical. The port only carries the image. However, this does not mean you cannot pair DVI with sound. There are ways to work around this limitation.
How to Transfer Audio Over DVI
So, how do you handle sound if your display setup depends on DVI? Luckily, there are practical solutions that combine audio with video, even when using this older standard. Here are the main approaches.
Use a DVI to HDMI Adapter
One of the most common methods is using a DVI digital audio to HDMI adapter. These small devices allow you to connect a DVI output to an HDMI input. The adapter can carry both video and audio with certain graphics cards.
Connect with an HDMI + Audio Splitter.
Another option is using a cable HDMI DVI audio splitter. This tool merges HDMI and audio connections into one cable for the display. It is helpful when your monitor accepts HDMI, but your PC only has DVI. HDMI to DVI with audio is a practical setup in that case.
Pair with Separate Audio Cables
The easiest fix is simply using a separate audio line in many cases. An example of this can be that you can run a 3.5mm jack from the computer’s sound port to the monitor’s audio input or external speakers. This is common in setups where the DVI port is used for video only. It might not look too elegant, but it gets the job done without extra adapters.
Use a Converter Box
A converter box can help if you want a one-cable solution. Devices combine signals and send them through HDMI. Keep in mind that they might be bulkier than an adapter. However, they can solve compatibility issues. A converter ensures that DVI to HDMI audio passes properly to TVs or monitors.
Upgrade to HDMI if Possible
Upgrading to HDMI cables simplifies things, and it is the last option. HDMI merges both video and sound into one line. Comparing the DVI cable vs. the HDMI cable, the HDMI clearly wins for modern setups. But for older machines that still rely on a PC DVI cable, the above solutions remain valid.
Takeaway
DVI remains reliable for video. But it requires adapters or separate cables for sound. HDMI may be more convenient today, but DVI still serves many setups well with the right adjustments. That said, solutions like adapters, splitters, and separate cords allow you to enjoy both visuals and audio together.

FAQs
1. Does DVI carry audio like HDMI?
No. DVI does not carry audio the same way HDMI does. It was built strictly for video signals without sound support.
2. Can DVI transfer sound with an adapter?
Yes. Only if your graphics card supports audio through its DVI output. Otherwise, a separate audio connection is needed.
3. What is a DVI cable used for?
A DVI video cable is mainly used to connect computers to monitors or projectors, and it transfers high-quality video signals.
4. Does a VGA cable transmit sound?
No, VGA is similar to DVI in this respect. Both standards were designed to carry video only, without audio support.
5. Which is better for sound, DVI or HDMI?
HDMI is better because it combines both video and audio in a single cable. DVI requires an additional step for audio.
