Incidentally, I was just looking at the Audio Devices in Control Panel and there are 3 : 1) AMD HDMI Output which has "not plugged in" below it 2) Speakers - which are the default and 3) Realtek Digital Output is says "Ready" - but when I click on it no sound comes out, but the sound bar moves up and down. Do these make any difference to the problem ? I have seen them before and the HDMI Output is always "not plugged in", even when I have connected the HDMI visual cable.
