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.
-
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
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.
