Smart Board Sound Not Working - No Sound From Smart Board

If you have a Smart Board and you find that there is no sound coming out of the speakers then check one thing first, that the speakers are switched on! There is a switch on the speakers on the underside that turns them on and off.

This switch is so tiny that most people don't know that it even exists!

I checked all the cabling and determined that the fault in our case was either the speakers themselves or one of the cables. Then I discovered the switch!!

If you still have a problem then take another set of speakers and plug them directly in the back of the PC. If all is fine then there is no problem with the PC and its sound output. Next try plugging the speakers into the leads that come out the back of the projector. In our case we run an HDMI (which carries both video and audio) into the projector and another lead out of the projector that goes to the speakers.

If you follow these steps, you should identify the source of your problem. It's unlikely that any cables are broken. Be sure to check the power adapter for the speakers, is it plugged in and working?
