VGA cables are commonly used to connect computers to monitors or TVs, but they only carry video signals. This means that if you want to transmit sound from your PC to your TV, you will need a separate audio cable. The standard cable for this purpose is a 3.5mm audio jack, which can be purchased at most electronics stores. One end of the audio cable should be connected to the headphone jack on your PC, while the other end should be connected to the audio input on your TV. In some cases, you may need to adjust the settings on your PC to control the sound output through the headphone jack.

What You'll Learn
VGA cables only transmit video signals
VGA cables are a type of Video Graphics Array cable that connects a computer or any other device to a monitor or another display screen. They are commonly used to connect older computers or devices to monitors compatible with VGA input. The cable contains multiple wires that transmit the video signal, such as red, green, blue, horizontal, and vertical sync signals. These signals combine and are sent through the connection to display a full image on the screen.
It is important to note that some older TVs and scalers can receive and playback both video and audio signals from a VGA cable. However, this is not a common feature, and most modern devices will require a separate audio connection.
VGA cables are still widely used, despite the increasing popularity of newer digital interfaces such as DVI, HDMI, and DisplayPort. VGA cables are advantageous in certain situations due to their ability to transmit analog signals over long distances without the same compatibility issues or degradation that digital signals may face. Additionally, VGA cables are generally more affordable than the latest digital interface cables, making them a budget-friendly option.
In conclusion, while VGA cables are versatile and commonly used for transmitting video signals, they do not carry audio. To transmit sound alongside video, a separate audio cable is required.

You need a separate audio cable for sound
When connecting a device to a TV using a VGA cable, you will need a separate audio cable to transmit sound. VGA cables are video-only, so they do not carry an audio signal. This means that if you want to hear the audio from your device through your TV, you will need to use an additional cable.
To transmit sound, you can use a standard 3.5mm audio jack cable, connecting it from the headphone or audio-out port on your device to the audio-in port on your TV. Depending on your TV model, you may need to use an RCA-to-aux connector or a small adapter to convert RCA to 3.5mm. Some older TVs and scalers can receive and play back both audio and video signals together, but for most setups, a separate audio cable is required.
After connecting the VGA and audio cables, you may need to adjust the settings on your device to ensure the sound is directed through the VGA connection. Refer to your device's manual for specific instructions, as the steps may vary depending on the device and operating system. It is also important to ensure that your TV is set as the default audio playback device in your system preferences or audio settings.
Additionally, it is worth noting that some TVs and graphics cards support HDMI connections, which can transmit both audio and video signals through a single cable. If your TV and device have HDMI ports, you may consider using an HDMI cable instead of VGA and separate audio cables for a more streamlined setup. However, adapters or converters may be necessary, depending on the specific ports available on your device and TV.
In summary, when using a VGA cable to connect a device to a TV, a separate audio cable is required to transmit sound. By using a standard 3.5mm audio jack cable or appropriate adapters, you can connect your device's audio output to the TV's audio input. Don't forget to adjust your device and TV settings to ensure the audio is directed and played back correctly through your desired output.

Some older TVs can receive and play both signals
When connecting a device to a TV using a VGA cable, you may need a separate audio cable for sound. The VGA cable only transmits video, so you will need to connect an additional cable from your device's audio output or headphone port to the TV's audio input. However, some older TVs and scalers can receive and play both audio and video signals through the VGA connection.
To clarify, the VGA cable itself does not carry sound. If you are using a D-Sub connection, audio is not possible through the VGA cable. You will need to connect a separate audio cable from your device to the TV. This can be a standard 3.5mm audio jack, connecting the headphone jack on your device to the audio input on the TV.
It is worth noting that some TVs may have specific requirements for audio input. For example, RCA stereo plugs may be needed, or you may need to use an RCA-to-aux connector if your TV does not have the appropriate inputs. Additionally, you may need to adjust settings on your device or TV to ensure the audio is directed to the correct output.
While most modern TVs require a separate audio connection, some older TVs are capable of receiving and playing both audio and video signals through the VGA connection. This may be due to the specific inputs and connectors available on these older TVs, or there may be certain settings that allow for combined AV audio and VGA input. If you are using an older TV, it is worth checking if it can receive and playback both signals before assuming a separate audio cable is necessary.
In summary, while the VGA cable only transmits video, some older TVs are capable of receiving and playing back audio and video signals through the VGA connection. For newer TVs or those without this capability, a separate audio cable is required to transmit sound from your device to the TV.

VGA cables with 3.5mm audio jacks exist
VGA cables are commonly used to transmit video signals from a source device, such as a computer or laptop, to a display device like a monitor or TV. However, standard VGA cables do not carry audio, so you will need a separate audio cable to transmit sound.
To address this, some VGA cables have been designed with an additional 3.5mm audio jack, allowing for both video and audio transmission through a single cable. These combination cables are known as VGA + 3.5mm Stereo Audio A/V Cables. They are particularly useful when you need to add audio without the hassle of an extra cable.
The 3.5mm audio jack on these cables typically extends a few inches away from the VGA connector on both the source and display sides, making it convenient for connecting to audio and VGA ports that may be located on opposite sides of a device. This design ensures easy connectivity without the clutter of excess cabling.
These VGA + 3.5mm audio cables are available in various lengths, such as 3ft (0.9m) or 35ft, to accommodate different setup requirements. They are also EDID compliant and CMG-rated, making them suitable for in-wall installations and applications requiring high-resolution video and stereo audio.

You may need to adjust settings on your PC
If you're connecting a PC to a TV using a VGA cable, you'll need to take care of the audio separately. The VGA cable only transmits video, so you'll need to use an additional audio cable to get sound from your PC to your TV.
First, make sure you have the correct cables. You'll need a VGA cable to connect your PC to your TV, and a 3.5mm audio cable to connect the headphone jack on your PC to the audio input on your TV.
Once you have the necessary cables, follow these steps:
- Connect the VGA cable from your PC to the TV.
- Connect the 3.5mm audio cable from the headphone jack on your PC to the audio input on the TV. This is usually labelled as "PC-IN" or something similar.
- Switch the TV input to the correct source. If your TV doesn't automatically detect the new connection, you'll need to manually change the input to VGA or HDMI (if you're using a VGA-to-HDMI adapter).
- Adjust the projection settings on your PC (optional). By default, your PC's screen should be mirrored on the TV. If you want to change this, press the Windows key + P on your keyboard to open the Project menu, and select your preferred option.
After connecting the cables and adjusting the TV input, you should be able to get video and audio from your PC to your TV. However, you may need to adjust settings on your PC to control the headphone jack sound. Refer to your PC manufacturer's manual for specific instructions on how to do this, as it may vary depending on your device.
Additionally, if your TV doesn't have a VGA port, you can use a VGA-to-HDMI converter. As you're converting from analog to digital, the converter will need power, usually through a USB cable. Make sure to purchase the correct type of converter (VGA to HDMI) and not the reverse.
