I recently upgraded to windows 10 and about a week ago I started having issues with my sound that I never had before. The sound will pop and crack and the volume fluctuates then either get quiet or really loud like someone kicked up the amp. I have uninstalled the diver and reinstalled it, tried different ones, tried a ton of different format settings, turning off enhancements you name it. I'm out of ideas please help. I'm starting to think it may be the sound card itself or the mobo but I have no idea how to check if its those things.
