Solving Image or Sound Problems
Solutions to Sound Problems
If there is no sound 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 on the projector or a source button on
the remote control 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.
• Disconnect the audio cable, and then reconnect it.
• 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.
• Select the correct audio input in the A/V Settings setting in the
projector's Extended menu.
• 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 in the projector's
ECO menu and make sure the A/V Settings options are set correctly in
the projector's 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.
• If the volume for the computer is set to the minimum while the
projector is set to the maximum, the noise may be mixed. Turn up the
computer's volume and turn down the projector's volume. (When you
use EasyMP Network Projection, EasyMP Multi PC Projection, USB
Display or Quick Wireless Connection.)
