There's part of the problem. ALSA has advanced enough that the best way to improve sound handling is to uninstall Pulseaudio. Why polish a turd when there's a perfectly good toilet handy?
Too many confuse "different" with improved. To really be an improvement, it must either do something useful that the old way couldn't do (or be made to do), or it must do it much more elegantly than the old way could.
I've got Linux with pulseaudio on my phone, it has to handle all kinds of audio routing between the ear piece, speaker, audio jack, bluetooth headset, and to do it all as seamlessly as possible. Can ALSA do this? because pulseaudio seems to handle it well.
Now I admit that this is not exactly a typical usecase, and indeed if you only have one thing you want to output audio to then simply using ALSA is more than adequate. This is perhaps one of the main issues facing the Linux ecosystem, everyone has wildly different usecases and expectations for their software and in the end you get a bit of an overengineered jack-of-all-trades without being good at any one thing.
