We have a ikon 900 projector and we can't get any sound to play when playing a movie. I hear sounds when moving thru the menu but when a movie is playing no sound.
It may not take the audio off the HDMI input. You may need to add a connection from the analog audio output of your source to the audio input of projector to get sound. If your source doesn't have audio out you would need an HDMI switch with audio extraction like this one. http/www.monoprice.com/Product?p_id=5557&kpid=105557&gclid=CPPY2sLnwcYCFYIXHwodhY0FTw
