What Should I Do If My Mini Projector’s Sound Is Not Working?

If you project a video with your mini projector and you realize that the sound is not working, do not think too much of it as a big issue. It could just be a minor issue:

Check to See if the Projector’s Sound Settings have been Set Right

The first thing to do regarding this issue is to check if the settings have been set correctly. In some instances, the projector’s sound may have been turned too low and become inaudible, or it has been put on mute. To fix the volume settings of your mini projector, you should:

  • Adjust the projector’s volume by increasing it. If you have your remote control, you can press the “+” to turn the volume up. If your mini projector does not have a remote control, press the “+” button on the projector’s control panel.
  • If adjusting the volume does not work, then perhaps the sound may have been muted. To unmute it, press the A/V button on the remote control.
  • If you are streaming with an app on your mini projector, check the sound settings on the app to see if it is low or has been muted. If it is, just adjust the sound settings.

Check to See If the Audio Output from the Connected Device

If you have tried adjusting the sound settings and still are not hearing any sound from your mini projector, check the connected device to see the audio output.

Whether the connected device is a computer, smartphone or TV, you may have chosen the wrong audio output. Sometimes, you will still hear the sound from the connected device’s speaker rather than your projector’s speaker.

Regardless of your device, you have to go to the device’s sound settings and check the sound output. Change the sound output to your projector if it has not been set. If you do not see your projector’s name listed in the sound output, check the audio input cable to see that it has been plugged into both your device and projector correctly. If it does not work, try changing the ports or the cable.

How to set the audio output on your laptop to your projector

  • Click on start and scroll down to the “S” column. Click on settings.
  • Click on “System.”
  • Scroll to the input section and click on the drop-down menu
  • From the drop-down menu, select your projector.

Update Outdated App

Your mini projector’s associated applications may not be updated, resulting in minor technical problems that can interfere with your sound. Check your projector to see if these apps have any new updates so that you update them.

Once you are done installing the updates, any issue associated with the projector’s sound will automatically be rectified.
