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
mute button on the
remote control to resume audio if it was temporarily muted. - 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 (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 Other Than HDMI3 (Game) to ARC/Optical (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 menu.
