If there is no sound when you expect it or the
volume is too low or high, try the following solutions:
- You must
connect external speakers to the projector to hear sound.
- Adjust the
projector's volume settings.
- Press the Shutter
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.
- Check the cable connection between the projector and
your video source.
- Check the audio cable connections between the
projector and your video source.
- If you do not hear sound from an HDMI source, set
Sound Output Format to
PCM in the Sound menu.
- 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 you want to use a connected audio source when the
projector is off, set the Quick
Startup option to Off 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]).
