Epson Projector Sound Not Working – Fixed in 6 Easy Steps!
Note: Have you tried unplugging the Epson projector from the power for ~60 seconds?
1. Check if the Projector Has Speakers
The first and most important step is to ensure the Epson projector has built-in speakers that can be used as an audio output.
If not, the only way to hear your projector’s audio is by connecting an external device or a speaker system that matches the projector’s audio output ports/plugs.
The main way of knowing whether your Epson projector has speakers or not is the year it was released.
- Well, projectors released before 2004 and 2005 may not come with built-in speakers.
Nonetheless, there are several methods you could also use for identification!
Method #1 Look for Physical Features
Before reading the projector’s manual and specifications, look for basic physical features for speakers, such as speaker grilles, audio ports, and an audio input port.
Method #2 Consult with the User Manual
If your projector’s physical appearance doesn’t tell you much, you can quickly consult the user manual and learn whether your model comes with built-in audio speakers.
Method #3 Use the On-Screen Menu
If your Epson projector features audio settings such as “Volume Control,” “Audio Source” or “Mute,” it is guaranteed to have built-in speakers that are used by default.
Tip: You could also check your Epson projector’s model online for a full list of the specifications!
2. Adjust Epson’s Volume Settings
Misconfigured audio settings are among the leading reasons why the sound not working on the Epson projector.
So, the next step is to first ensure that the projector hasn’t been muted and then check if the volume is increased to audible levels through the device menu and settings.
So, let’s try regulating the projector’s volume first!
2.1 How to Adjust the Volume Of Epson Projector?
You can easily adjust the volume status of the Epson projector by pressing the “Volume Up” and “Volume Down” buttons on the frontal control panel of the projector.
Ensure the volume is set to at least 50% throughout the entirety of the device, so you can test the output at all times.
2.2 How to Mute/Unmute the Epson Projector?
To change the mute status of the projector, press the “A/V Mute” button found on the projector.
Shortly after, an icon displaying the current mute status will appear on the display. If the icon is crossed, it means that the projector is currently muted.
3. Configure Epson’s Source Selection
The audio output settings of your Epson projector must be configured accordingly to the setup and presence of third-party speakers or external devices.
If you’ve connected a sound set to your projector and wish to no longer use the built-in speaker, you must specify the correct source within the settings menu.
Hence, here’s how to change the source on your Epson projector:
- Use the top panel buttons to access the projector menu.
- Now, navigate to the “Audio Settings” tab within the options.
- Go to “Audio Output” or “Audio Source” based on the model.
- Pick “External Speakers/Audio Output” or “Internal Speakers.”
Note: If your projector has no built-in speakers, then the only options will be the HDMI and audio output inputs of the device.
4. Inspect the HDMI or the Audio Cable
If you’re re-routing the projector’s audio to a third-party device, such as a computer, laptop, or a Blu-ray player for example, there could be a fault with the cable’s audio transmission.
There’s an onset of steps to try to validate the connection between your projector and third-party device, so proceed with the steps below!
Step #1 Inspect the Physical Condition
The first and most important step is to ensure that the HDMI cable or audio cable used with the projector is in good condition.
Search for any peripheral damage inflicted to the cable, including rips, cuts, bent connectors, or burnt areas.
Step #2 Switch Through a Different Input
If possible, connect the HDMI or audio cable to a different input on your external device or on the Epson projector itself.
Test with all available inputs and don’t forget to cycle to the respective source on your projector and third-party device.
Step #3 Replace the Cable
If nothing helps, perhaps, the cable is no longer working due to a malfunction.
We suggest installing a cable with proven functionality to effortlessly tell if the audio output of the Epson projector works at all.
5. Check your Computer or Video Source (External Audio)
If the Epson projector sound is not working with an external audio system or a device, the next thing to check is the external device’s audio output and volume settings.
Whether you’re using a computer, a laptop, a TV, or any type of audio conversion device, you must set it to the same input as the Epson projector.
So, based on your device, conduct the following steps:
Step #1 Check the Volume/Mute Levels
This step is common regardless of the device type connected to your projector.
Check if your PC, laptop, DVD player, or TV’s volume levels are increased and ensure the “Mute” status is also “OFF.”
Step #2 Configure the Audio Output
On most devices, adjusting the audio output device must be done manually.
So, if you’re on a PC, search for the volume mixer in the system tray and if you’re on TV, consult with the user manual for the exact steps to change the output.
Step #3 Update the Device’s OS
It is also recommended to ensure the external device runs on the most current firmware, as it could be incompatible with the audio drivers used by the Epson projector.
You can often check for newer OS versions through the “Firmware” menu of the device.
6. Restore the Projector to Factory Defaults
If you still fail to restore the audio output of the Epson projector, a factory reset might help.
The procedure will erase all of your projector’s broadcasting, video, and audio settings and hopefully eliminate all underlying errors along with the system configuration.
Follow these instructions to reset Epson to factory defaults:
- Press the “Home” button on the Epson remote control.
- Select the “Settings” icon found in the upper-right corner.
- Go to “Device Preferences” and press the “Enter” button.
- Select “Reset” and press “Enter” again to proceed further.
- Select “Reset” to confirm and wait for the reset to initiate.
Once your projector enters the factory reset state, cease all interactions and wait for at least 1–2 minutes to pass.
During that time, your projector will be inactive, thus, pressing any of the keys on the remote or the projector’s top panel won’t have any effect.
Note: To factory reset the Epson projector, it must currently be connected via HDMI to a TV or a monitor (broadcast viewing device.)
