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 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 the USB Display function, turn on the Output audio from the projector setting in the
Epson USB Display Settings program on your computer.
• 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 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.
