Yes they do, natively.

I'm quite sure about the "natively" part. Not 100% sure because until
yesterday I didn't really know how components from the sound stack fit
together. I did some reading and I think I get it now but you never
know... As proof that PulseAudio is accessed natively:

sudo lsof /usr/lib64/alsa-lib/libasound_module_pcm_pulse.so
kded4   1504 catalin mem    REG  253,2    27408 1464302

sudo lsof /usr/lib64/libpulse.so.0.14.3 | grep -e 'vlc\|amarok'
amarok    3215 catalin mem    REG  253,2   303960 1452792
vlc       5553 catalin mem    REG  253,2   303960 1452792

sudo lsof /usr/lib/libpulse.so.0.14.3
skype   4664 catalin mem    REG  253,2   322372 1457169
