EPSON Projector Sound not Working (Causes & Fixes)

Using your projector’s speaker for sound can be helpful when you do not have an external speaker. However, there could be times when you project a video and the projector does not produce sound. This can be frustrating if the device you are projecting from does not have a speaker loud enough or its speaker is faulty. It can also be an issue if you are in the middle of a presentation and playing a video for an audience. There are several reasons why this would happen.

If your EPSON projector’s sound is not working, you must first check if you have muted the projector or the device from which you are projecting. A faulty HDMI cable or audio source can be a cause. If your projector’s speaker is faulty, it may not produce any sound or produce weird sounds. In some instances, the projector may not even have an internal speaker. You can get your EPSON projector speaker to work by unmuting it or turning up the volume from your projector or the connected device. Change the sound input source cable if it is broken. Sometimes, restarting or restoring the projector to factory settings can help. If all the solutions fail, connect the projector to an external speaker.

Follow this article to know what can cause your projector’s sound to stop working and how you can fix it.

Why is My EPSON Projector’s Sound not Working?

If it is your first time using the projector, you must check to see if it has internal speakers before attempting other checks. If the projector has internal speakers that are not working, then it could be due to the following reasons:

Your Volume may have Been Turned Down or Muted

Your projector’s speaker may not be working because the device’s volume may have been turned down or muted. If you check the projector and it has not been muted, you must check your laptop or the connected device.

Audio source problem

HDMIs are capable of transmitting audio and video signals. You must check to see if the cable has been fitted correctly into the projector and laptop port. If it is still not working, use different ports and try different HDMI cables. If your HDMI is working to project just visuals without sound, then it means that the cable cannot transmit audio signals.

If you are using a different audio input, it may be broken, or its port may be faulty.

A faulty or damaged internal speaker

If your projector’s speaker is faulty, it can interfere with its functioning. Sometimes, the wires connecting the speaker to the board may be broken. You will need a technician to take apart the projector to confirm this.

What Should I Do if My EPSON Projector is not Working

Unmute the projector and turn up the volume

If your projector has been muted, press the A/V Mute key on the remote to unmute it. Turn up the volume of the projector if necessary. If the laptop or TV you are projecting from has been muted, unmute it and turn up the volume.

Change the sound input source if the port or cable is broken

If you are connecting an HDMI cable to your projector, make sure to turn off the projector before plugging in the HDMI cable; if not, it may transmit the visual signals and leave the audio signals. If the problem persists, restart your laptop and projector.

If that does not solve the problem, set the output of the connected device to PCM.Try a different HDMI cable. It would help if you tried other HDMI ports; perhaps the one you are using is faulty.

If you are using a different audio cable, unplug it and plug it back into the projector.

If the sound is still not working you can try these other alternatives

  • Check your EPSON projector’s extended menu to see if the A/V settings have been set correctly.
  • If your connected device is a Mac, ensure that it supports audio through an HDMI connection.
  • Turn on the output audio from your EPSON projector’s setting if you are using a USB Display function. This setting will be available to you in the EPSON USB display software installed on your computer.

If the problem persists after these solutions, you can take the projector to a technician to open up the device to see if the speakers are in good shape.

If this solution seems too long for you, you can connect your projector to an external speaker with an audio jack or Bluetooth if the projector supports it.

If you connect your projector to an external speaker, it will automatically disable the internal speakers.
