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.
• 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 cable connection between the projector and your video source.
• 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.
• If you hear a hissing sound from your projector's speakers when projecting from a computer running
Windows 10 over a network, you may need to adjust the Windows 10 sound properties:
1. Right-click the speaker icon in the Windows taskbar and select
