If you've plugged your computer into a projector and the audio is only coming through the speakers in your laptop, you may need to switch the audio device. To do this:


  1. Click on the speaker icon in the bottom right-hand corner of your screen
  2. Click on the text at the top of the volume window
  3. Change the source to "Epson PJ"
  4. You may need to unplug the HDMI cable from the projector, and re-plug it in
