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 or 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.
- 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 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.
- Make sure
the Audio
Settings option is set to the correct audio port for
your video device.
- 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.
