I have noticed this more in the newer dev builds since they removed the Audio framelimiter. When I would drop frames it wasnt as jolting as now because the sound wouldnt stutter along with it. I could handle that part much more. Its also strange that your getting stutters without frames dropping. I havent noticed them on my side.
