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 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.
• 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.
• 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 the volume for the computer is set to the minimum while the projector's volume is set to maximum,
the sound level may be mixed. Turn up the computer's volume and decrease the projector's volume
(when using Epson iProjection [Windows/Mac]).
• Make sure the A/V Settings options are set up correctly in the Extended menu.
• If you turn the projector on immediately after turning it off, the cooling fans may run at high speed
momentarily and cause an unexpected noise. This is normal.
