So recently my computer's sound stopped working. Under device manager in the, "Sound/video and game controllers tab everything seems to be working properly. I have formatted my computer, so I have no spyware/viruses. I installed the drivers that came with my motherboard, my speakers work. Everything seems to be in order but no sound is coming out when I play music or test the speakers. I know the Speakers work because i've tested them out on another computer, so it must be a configuration problem, any ideas?
