Playing a music file today, I realised that I was only getting sound out of two of my Creative 5.1 speakers, left rear and right rear. Om investigation, I found that the audio settings had become set to "Desktop stereo speakers". I've reset this to "5.1 surround sound speakers" and rebooted (just to be sure). It's still set to this, but I still only get sound from the two rear speakers and a bit from the subwoofer, whatever I try. I've checked all the cabling to make sure nothing had come loose. Everything has always been fine until now. Any ideas how I get my 6-speaker sound back? I have a Creative Audigy card and Creative speakers.
