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
Sound Output Format to
PCM 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 (ARC) port
Enable HDMI CEC in
the Settings menu
Enable HDMI2 ARC
in the Settings menu
Set Sound Output
Device to ARC in the Sound
menu
Set Sound Output
Format to 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 from the projector's
speakers, try setting Sound Output
Device to Speaker and
Sound Output Format to
PCM in the Sound menu.
If you want to output audio to an external audio
device using an optical digital audio cable, set Sound Output Format to PCM in the Sound menu.
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 directly to
your speaker system.
If you do not hear audio from your projector
speakers, make sure the audio isn't being output to a Bluetooth
speaker.
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.
