I had some speakers (labtec ones with 2 plug in thingys at the back) and they suddenly stopped working. i just presumed the speakers had broke as I checked all the sound devices etc and my computer said they were all working fine and no conflictions. Anyway, I've got a new pair of speakers again, labtec ones but this time with just one plug in thingy and i still can't get em to work. I've tried everything, all the troubleshooter options and everything, please help!
