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 audio cable connections between the projector and your video
source.
• 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 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 in the projector's Extended menu.

• If you do not hear sound from an HDMI source, set the connected device to
PCM output.
• When you are connecting the projector to a Mac using an HDMI cable,
make sure your Mac supports audio through the HDMI port. If not, you
need to connect an audio cable.

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 Epson
iProjection (Windows/Mac) or USB Display.)
