It might not actually matter. Reboot Windows. Sound starts playing out of your monitor, which you didn't even know had speakers. How do you fix it?

(The answer is not to type "sound" into the search bar. That takes you to the "new" sound control panel, which doesn't have all the old features, including disabling sound devices. So you have to open the control panel, go to Devices & Sound, and then you can search around to disable a device.)

The fundamental difference between Windows and Linux here is that if you write an instructional blog post to fix this problem for Windows, you can put some drive-by malware installer on it and make some money. You could obviously malware up similar Linux documentation, but by the time you get discovered you will have only infected 1 person, simply because it's much less widely used. Unfortunate!
