  • Press the A/V Mute button on the remote control to resume video and audio if they were temporarily stopped.


  • Press the Source Search button to switch to the correct input source, if necessary.


  • 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.

  • If you are using a Mac and you do not hear sound from an HDMI source, make sure your Mac supports audio through the HDMI port. If not, you need to connect an audio cable.
