"pulseaudio doesn't work" meme in 2020, lol.
Windows audio is a completely solved problem, right? Let's see some web search results for variations of "windows audio problem":

Some lets-players I watch regularly complain about how W10 updates break their audio capture / microphone settings. They work around it by uninstalling the update and trying as hard as possible to not let it be reinstalled automatically.

Like I said, not only are there problems, but nobody knows how to figure out what the problem is. Just "run the built-in troubleshooter" (which both clueful and clueless Windows users will tell you rarely fixes anything), "update your drivers", "install Windows updates", "restart your computer".
When I have issues with OSS on Linux, I have logs with filenames and distinctive error messages, publicly viewable sources that I can correlate the logs to if I want to, and forums of other people who can do that if I don't. If it's an absolutely novel problem, I can contact the authors of the code and have a high expectation of getting a response. If it's an issue that needs a fix, I can track the progress and release of the fix.
And before you say "I don't have any of these problems with audio on Windows", I too haven't had any problems with pulseaudio for the almost 10 years that I've used it.
