My computer is having frequent intermittent cpu usage spikes, during which all sound pauses. I can usually cause it to happen by reloading a website, but it will happen rather or not I'm doing anything. I've tried reinstalling my sound drivers, and it seemed to fix itself, but after a few days, it was doing it again. Each pause lasts 2-3 seconds, and then continues where it left off. So if someone speaking is midword when a pause happens, they'll finish the word when it ends. It almost always corresponds with 100% cpu usage, but I've been unable to identify anything that is specifically causing the cpu spikes. I haven't noticed any other slowdown from the spikes. A game won't experience lag, or lose framerate. Youtube will pause the video once the spike ends to allow the sound to catch up.
