Or perhaps Ubuntu users have higher expectations of being able to "just buy random hardware" or include more non-technical users.
I can't really tell, as I'm not in either group, nor have ever experienced any of the dreaded Pulse Audio problems. I'm not saying I like it - but only because it "just works" for me, enough that I have not bothered to learn enough about it to have any reasons to like or dislike it. Which I suppose means I really ought to like it given how troublesome audio on Linux has been at various times over the years.
