I am running Windows 10 Pro x64.
Sometimes, without any obvious reason or trigger, all audio and video playback - no matter if it's youtube, VLC, Spotify, the Windows sounds - starts stuttering uniformly and does not stop until reboot.
I have installed the latest graphics, chipset and audio drivers - no change.
