There is no sound. What should I do?

• If there is no sound when you expect it or the volume is too low or high, try the following solutions:

  • Adjust the projector's volume settings.
  • Press the A/V Mute or Mute button on the remote control to resume video and audio if they were temporarily stopped.
  • Make sure the Audio Out Device settings are correct.
  • Make sure the Bluetooth Audio settings are correct and that the Bluetooth audio device is paired to the projector.
  • Check the volume level on the paired Bluetooth audio device.
  • Check your computer or video source to make sure the volume is turned up and the audio output is set for the correct source.
  • Check the audio cable connections between the projector and your video source
  • Make sure any connected audio cables are labeled "No Resistance."
  • If you turn the projector on immediately after turning it off, the cooling fans may run at high speed momentarily and cause an unexpected noise. This is normal.
