Solutions to Sound Problems
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 button on the projector remote control to resume video and audio if they were
temporarily stopped.
• Make sure the Audio Out Device settings are correct.
• 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.
• 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.
