PowerLite 470 XGA 3LCD Projector
Why isn't there any sound?
Try the following solutions:
Adjust the projector's volume settings or press the
volume button on the remote control to turn up the volume.
A/V Mute button on the remote control to resume video and audio if they were temporarily stopped.
Source 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.
Make sure any connected audio cables are labelled "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 turn on the Standby Audio option.
Note: Try setting the Audio Input to Auto or desired audio input source in the projector's Extended settings.
