Code: sudo apt-get remove pulseaudio gstreamer0.10-pulseaudio

I just did a clean install of Ubutnu 10.04. I then removed pulseaudio and gstreamer0.10-pulseaudio using:APT then removed a bunch of other pulseaudio related packages. It also removed the ubuntu-desktop metapackage.With some trepidation, I let APT do it's thing. I have since logged out and rebooted with no ill effects. Sound works fine with alsa; and the ubuntu desktop is intact with all my settings preserved.Pulse Audio is less of a resource hog in 10.04 than it was in 9.10. However, it still was using more of my CPU (around 3-4% with one sound app running, and up to 12-14% with 2 sound apps running) than alsa, so I removed it! I have no need for pulse audio.Hope this helps.
