Projectors aren’t just for movies and business presentations anymore! With the introduction of the home theater or home entertainment system, they are rapidly becoming a standard in homes as well. In light of the foregoing, it is true that sound has grown in significance in the context of home entertainment systems. It helps to have some sort of sound output available even when you’re connecting your laptop to a projector to present a slideshow with lots of graphs and tables.
How to get sound from the computer to the projector exactly? It depends on the ports your projector has available, the devices or media you can connect to it, and whether you plan to use the home theater system’s audio system or a Bluetooth speaker for your audio needs.

Do All Video Projectors Have No Sound?
Not every video projector is silent. Many contemporary video projectors connect using HDMI, which supports both audio and video, or other AV ports in addition to a 35mm jack for sound. These most recent projectors can also be used as televisions, which are distinguished by having built-in speakers.
- Most Video Projectors Are Silent: One the one hand, the majority of even purportedly modern digital video projectors are soundless. On the other hand, there are projectors that have built-in speakers or stereos that allow sound to pass through. However, similar to how filmmakers don’t bother with built-in speakers in camcorders, the majority of home theater enthusiasts don’t bother with projector built-in speakers. Other than what is built-in, there are better ways to “get” sound.
- Projectors in Home Theater Settings: In order to replicate the surround-sound experience found in real movie theaters but in a home setting, there are a plethora of speakers, soundbars, bases, subwoofers, and stereos available. Despite having built-in stereos, the majority of projector owners are more concerned with their cable box’s or Blu-ray player’s ability to connect to their sound system than they are with the projector’s speaker. Similar holds true for an HDTV’s speakers.
- There are built-in speakers in many compact or pico projectors: Even though not all video projectors are silent, the majority of them are, particularly those used in home theaters that have the option to connect the audio to a different sound system. However, especially those that are small or portable, more and more video projectors now come with a built-in stereo. They are designed for mobile setups where carrying a sound system around isn’t as practical.
- A Home Cinema Experience: If you don’t want to bother turning on your speakers or anything like that, you can also use these speakers to watch a movie at home. You can watch on a screen that is much bigger than the biggest TV screens thanks to the projector’s ability to adjust projection between 80 inches and 150 inches. On top of that, the built-in speakers work like PC laptop speakers that can turn your pico projector just like your
- A projector with its own sound that resembles a television 4K used to only be available for computer monitors and televisions. But now that projectors with HDR10 are available, you can view breathtaking visuals with sharper imagery, fuller saturation, higher contrast, and deeper colors overall. This also implies that your 2000:1 native contrast projector serves double duty as both a movie projector and an alternative TV display with a built-in speaker system.
- A Truly Portable Sound System The main benefit of these projectors with speakers is that you can use a projector and a screen without also carrying a full sound system when you’re traveling to a conference or want to watch something when there isn’t a TV nearby. This complements other portability attributes like an ultra-short throw distance of only 7.2 inches away, which enables you to project at any blackboard or blank wall in addition to a screen.
- Laser Projectors and Built-In Speakers Work Together: Additionally, laser technology is available with industrial-grade lamps that have a 25,000-hour lifespan in many portable or compact projector devices. These devices often have an integrated soundbar or speaker. Thanks to HDMI technology, you are able to take advantage of these display options for up to 4 hours per day for the ensuing 17 years, along with the sound. For added security, these portable laser projectors come with infrared remote controls for volume adjustments.
What Prevents Sound From Going From A Projector To Speakers?
The potential problems that could prevent sound from a projector from reaching speakers are almost limitless due to the wide variety of audio and video sources, projector configurations, and speaker configurations.
The most frequent issues that you might be experiencing are listed below:
- Bad cables
- Bad connections
- Loose connections
- Projector sound settings
- Audio input device settings
- Software issues
How To Get Sound From A Projector To Speakers?
You’ll need to try a few fixes before you find the one that works in order to solve your issue and successfully get sound from your projector to your speakers. Skip the first one and move on to the next if it doesn’t apply to you because of your particular hardware configuration.
- Look at your connections. Remove the audio/video cable from the projector and re-plug it, making sure to seat each end firmly. The cable(s) that connect to your speakers should then be connected using the same procedure as before. You won’t hear anything if one or more of the connections is loose or not completely seated.
- Verify the type of your connection. You won’t hear any sound if you connect your projector to an audio/video device, such as a laptop, using a VGA cable because VGA only supports video. The same is true if you connected your projector to an audio/video source using a single video RCA cable or three RGB RCA cables. You must use an additional cable, such as an optical audio cable, RCA audio cables, or a 3.5mm audio cable, to transmit sound when using VGA or RCA cables for video. The left and right channel RCA cables are required to send sound when using RCA cables.
- If the cables you use to connect your audio/video source to your projector or your projector to your speakers are damaged, try using new ones. Sometimes jiggling or moving a broken cable will make sound fade in and out.
- Verify the audio input device. Verify that the appropriate audio output is chosen and that the computer or laptop is not muted if you have connected a computer or laptop to your projector. Verify you haven’t muted or lowered the volume of the device if you’re using it to output audio and video to your projector.
- Verify the volume of the projector. You might have trouble hearing the speakers if the projector volume is turned down. You most definitely won’t if it’s muted.
- Verify the projector’s sound output source settings. Press the source button if your projector has one. If it doesn’t, follow the instructions provided by your projector to make sure the speakers are receiving the right audio source.
- Look at the speaker’s volume. Check the volume of your soundbar, receiver for home theater, or amplifier. Additionally, confirm that everything is turned on. Make sure the speakers are working and connect any additional audio sources you may have.
- Check the speaker’s input configuration. Make sure you’ve chosen the audio input for your projector if you’re using a soundbar or receiver that has multiple audio inputs. If at all possible, try plugging your projector into a different one and switching to that.
- Examine the software for updates. Make sure there aren’t any app updates available before using an app on your projector or connecting a device like a Fire Stick or Roku. Issues could arise if the app is out of date.
- Investigate any wireless interference. Remove any potential sources of interference if you’re using wireless technology, such as Bluetooth or WiFi, to connect to the speakers. If it’s possible, try moving the projector and speakers closer together and check their connections.
When it comes to using a projector with sound, you essentially have two choices. For the full cinematic or surround sound experience, connect the audio jack or additional HDMI cable to your home theater system speakers and stereos. This is similar to how your desktop has a separate speaker system because its internal speakers aren’t as advanced with HD sound.
You can also use a projector that has a built-in soundbar or speakers to provide the sound by connecting both the audio and the video cables to the same TV. Now that your projector has speakers and a screen, it can function as a TV set. Even a separate earphone or headphone output is an option, but it will need additional adapters and converters for safety.
