I do not know if they are affected too. I think the microphones in that range are actually associated with webcams, so they may actually be safe to include. However, many of those listed at gowdy.us in that range are pre-UVC gspca-supported webcams, not UVC webcams, and there appears to be at least one webcam outsude of that range (d001 - QuickCam Pro, also gspca).
