Solutions to Sound Problems
If there is no sound from the external speaker when you expect it or the volume is too low or high, try the
following solutions:
• You must connect external speakers to the projector to hear sound.
• Adjust the projector's volume settings.
• Make sure external speakers are connected.
• Press the A/V Mute button on the control panel or remote control to resume video and audio if they
were temporarily stopped.
• 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 out cable connection between the projector and your external speakers.
• If you do not hear sound from an HDMI source, set the connected device to PCM output.
• Make sure the connected audio cable is 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 directly to your
speaker system.
• If you want to use a connected audio source when the projector is off, set the Standby Mode option to
Communication On and make sure the A/V Settings options are set correctly.
• If you want to use a connected audio source when the projector isn't projecting any images, set the
Quick Startup option in the Operation menu to Off and make sure the A/V Output setting in the
Extended > A/V Settings menu is set to Always On.
