When those kind of audio glitches occur, it's typically because system resources have become depleted. You may have an application running which has a memory leak; consuming more and more memory as it continues to run. I'd suggest trying to replicate the situation and open the task monitor to see if that's the case, or to see if other applications / background tasks are running and taking resources.
Start by disabling any backgrounded software, 3rd-party security / antivirus applications, drive indexing or search indexing, etc.
