This has to do with not only with the generic Microsoft Audio Drivers, but is also dictated by the actual audio device on your laptop's motherboard. You can only push any audio device ( onboard or otherwise ) as far as it physically can go. Since the stock audio hardware on a laptop is for basic audio observance, there will always be some limitations; via the hardware and or driver. As we enhance our audio recording/listening abilities via adding any of the various external audio interfaces that are out on the market; when we unplug them and operate on the laptop solely... we leave ourselves to the whims of the manufacturer and the basic driver that comes with it. Computers are only as powerful as the weakest link and driver that comes along with it. As they are primarily designed for word processing and internet, onboard audio ( no matter how " stock " it may be ) is more of an afterthought when it comes to the total package that is one's computer.
A great example of this is that I am personally running a Studio 192 on my Windows 10 PC. I have had to disable a USB webcam w/mic, that I have installed for video conferencing, when I am recording; as when it is active, it uses a generic Win10 audio driver and will interfere with higher sample rates I work in.
