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 or
Mute button on the remote
control to resume video and audio if they were temporarily
stopped.
- Press the
Source 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.
- 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
connected an audio device to the projector's Audio Out port, the internal speaker is
disabled. However, you can still control the volume level via the
remote control.
- 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.
