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.
- Try disconnecting and reconnecting the audio
cable.
- 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
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 noise may be
mixed. Turn up the computer's volume and decrease the projector's
volume.
- Make sure the A/V
Settings options are set up correctly and the Audio Out setting is set to Auto.
- 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.
