Thank you for your clarification of the issues. I think pulseaudio just gives 
more control to adjust volume level of running applications as clients and 
provides a modular configuration compared to just using alsa. Bu I also think 
most of us don't need such control, we can just use a mixer of what we want 
and adjust everything manually (I mean which suits the situation). So, I 
assume that I don't really need pulseaudio.

I know alsa is always present. But if I don't remove pulse audio packages, 
there can be some misconfigurations (for example, alsamixer uses pulse audio as 
default and doesn't let me to adjust volume, but sure I can do alsamixer -Dhw 
for it, it is not a big deal). And removing alsa also removes ubuntu-desktop 
meta package or ubuntustudio-desktop meta package, though it is not important,  
I really wonder why such an unstable and conflicting thing like pulseaudio is a 
part of the desktop meta packages.
