There is no sound. What should I do?
Check that the volume setting is not turned all the way down and that the audio/visual cable is securely attached to both the projector and the audio source. Make sure the AV/Mute feature is not enabled. If it is, press the AV/Mute button one time to deactivate it. Also, the wrong source may be selected. Press the Source button on the remote control or control panel to select the proper source. Additionally, if there is still no sound, try connecting the speaker to the computer or video device to make sure that sound from the device is working. Always turn off equipment prior to changing cables.
