The built n sound on my ASRock 970 extreme 4 is not working. I have checked device settings, changed bios settings, tried multiple ports with multiple speakers. When I play something that has sound, I can go into audio control and see the sound spikes but can't hear it. Could there be any problem where anything is interfering with the motherboard and messing the sound up? Everything else works great besides the computer doesn't boot when the wireless USB adapter is plugged in. Should I just buy a new sound card?
