I've been using:
yum remove pulseaudio \
pavucontrol pulseaudio-utils pulseaudio-libs-zeroconf \
gstreamer-plugins-pulse pulseaudio-core-libs \
pulseaudio-libs-devel pulseaudio-module-zeroconf \
This leaves pulse-audio-libs, which I think is plugged in deeply into
the sound processing structure.
Make sure that you have all of the mixer settings set full 'ON' when you
test audio. It is really annoying to finally find out that the sound was
just turned down. Been there. No T-shirt. I use alsamixer-gui and then
aplay /usr/share/sounds/alsa/Front_Center.wav to test.
