I have a Gateway computer using Realtek audio and it has been fine for the past year that I've owned it. Sometime in the last 24 hours it has stopped playing sounds. Speakers are on, enabled, plugged in correctly, all devices are working, no obvious signs of conflicts etc. Nothing was changed in the hardware or software that I am aware of and sounds appear to play but nothing is heard. Speakers make a noise when plugging and unplugging them but that's all. Only two significant things in the past 24 hours that I can think of that may have affected it somehow... 1) Tried Norton Ghost for the first time but cntr alt deleted out of it when I saw it would take 7 hours 2) Electrical storm with lots of lightening but I unplugged everything fairly early on and nothing else seems to be broken. Thoughts?
