I would go so far as to say that a large part of why audio is such a CF under Linux is -- wait for it -- lack of real asynchronous I/O.
Audio is asynchronous by nature, and to do that right under Linux you need a "sound server" with all the additional overhead, jank, and shuffling of data between kernel and at least two different user spaces that implies. Audio under Linux was best with OSS, which was synchronous in nature and not suitable for professional applications. JACK mitigated that somewhat, but for an OS to do audio right you need a kernel-level async audio API like Core Audio or whatever Windows is doing these days.
I have a PC connected via on-board HDMI to a Denon AVR solely for the purpose of getting the audio to the amplifier. Windows doesn't let me use that audio interface without extending or mirroring my desktop to that HDMI port. Since there is no display connected to the AVR I don't want to extend the desktop, and mirroring heavily decreases performance of the system.
On Debian Sid the computer by default allows me to use the HDMI audio without doing anything to my desktop display. It seems the system realizes that there is no display connected to the AVR but it's still a valid sink for audio.
I use Linux regularly to record and edit audio, it's free , it works, and I dont have to worry my OS is active reducing the functionality of my equipment.
11 param functions don't say "power" to me. They say "poorly thought out API design". Much can be said for most Windows APIs in general.

It's not sophisticated enough or powerful enough to be the most used kernel on super computers (and in the world). Windows pretty much only dominates the desktop market. Servers, super computers, mainframes, etc, mostly use Linux.
A few years ago there was even a bug in Windows that caused degradation in network performance during multimedia playback that was directly connected with mechanisms employed by the Multimedia Class Scheduler Service (MMCSS), this is used on a lot of audio setups. If they can't even get audio setups right how can people consider anything Windows releases "sophisticated"?
It's made to do anything you throw at it I guess, it's definitely complicated, but powerful and sophisticated aren't words I would use to describe NT.
