What is ActivInspire?I have no sound on my activboard,prm-ab378-03



Make sure that the amplifier of the board is powered on. On
the left side of the board you should see the volume control amp. Make sure
that the standby light is green. Also make sure that you go into the sound
settings of your computer and see if promethean usb is listed for playback
options and select it if its not already selected.
