For me, it looks like a lie, because of no information about hardware, distro, kernel, etc.
For example, pulseaudio works fine for me for at least 6 years on 6 notebooks and 2 workstations of various vendors (HP, Dell, Acer, Medion). But if it will work badly under heavy load, then obvious command will fix that: `sudo renice -n -10 $(pgrep pulseaudio)` .
Assuming that other people are lying because they have trouble with things you like is paranoiac behavior. The almighty Linux desktop is not important enough to lie about.
I am leader of Linux User Group in my country, so I am aware about typical problems with Linux desktop. Last problem with PulseAudion on major distro, I heard off, was years ago.
