The motherboard has a version 1 and 2. I can't check what driver you are using or if this is a new or always did it problem.

Since the start of August I've been having an ongoing problem with my audio, where every 30-120 seconds the audio will cut out for about two seconds, when the audio resumes, it does a variety of things depending on what is playing the audio, in an HTML5 player (Youtube), the audio will resume where it left off, and the video will freeze until the audio has caught up. In VLC, the audio will resume where the video is (Alot of the time in VLC the audio will resume for a split second, then cut out again for about half a second, then resume as normal), in a game, I think the audio desyncs completely, since the audio resumes where it left off and the game does not freeze to allow the audio to catch up.
I use a Logitech G933 headset and have replaced the entire headset at one point (Due to a separate problem with the headset) with the same model to no avail, even so, I have run my audio through my seperate 'speakers' and the problem is still present. I have updated multiple drivers but none of them seem to affect the problem in any way, I have even done a system restore back to before the problem occurred, which solved nothing.
Any help would be immensely appreciated, thanks.
