How to disable pulseaudio on ubuntu 9.04
PLEASE DO NOT FOLLOW THE INSTRUCTIONS IN THIS POST UNLESS YOU KNOW WHAT YOU ARE DOING.
Pulse audio seems to be a constant source of trouble for me while providing no benefits at all (at least not any noticeable ones). So here's how to get rid of it:
Open /etc/X11/Xsession.d/70pulseaudio in a text editor and comment out everything (put a # in front of every line) and then save it.
This will prevent pulse audio from being started when you log in.
