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.
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.
If you do
not hear sound from an HDMI source, set the connected device to PCM
output.
If you want to output audio from the projector's speakers,
check that the Sound Output setting
is correct in the Sound menu.
If you want to output audio to an external audio device using
an HDMI cable, try the following solutions:
Make sure the HDMI cable is connected to the projector's
HDMI2 (eARC/ARC) port
Make sure the sound is output from the projector's speakers or
Optical Out port
Enable HDMI CEC in the Settings
menu
Enable HDMI2 ARC in the Settings
menu
Set Sound Output to ARC (PCM) in the Sound menu
Make sure the HDMI cable is compliant with HDMI ARC
Note: When
outputting audio to an external audio device that does not support
HDMI ARC using an HDMI cable, disable HDMI
CEC in the Settings menu.
If you want to output audio to an external audio device using
an optical digital audio cable, check that the Sound Output setting is correct in the Sound
