I was recording three episodes of the TV show, Star Wars: The Clone Wars, in which the first episode I recorded had audio distortion in it while the rest didn't have the problem. Additionally, I had recorded Star Wars: Battlefront II and some of the recorded video had audio distortion. Audio drivers for my computer have been updated and OS updates applied. I didn't have this issue for the first months after I built my computer (October-December).
The weird thing is, if separate microphone track is enabled, main audio track is indeed no longer corrupted, but the microphone track is. I am having this problem with the microphone audio track at the moment. Game audio is crystal clear but microphone has the same popping problem. So it is not really a solution but a workaround.
