Solutions to Sound Problems

If there is no sound when you expect it or the volume is too low, try the following solutions:
Adjust the projector's volume settings.
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 do not hear sound from an HDMI source, set the connected device to PCM output.
Make sure any connected audio cables are labeled "No Resistance".
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.
