Pulseaudio makes sound skip

[Aaron]

Hi there people !

I have a small issue, since 8.04 my sound skips when pulseaudio is 
running. Killing pulseaudio stops any skipping from happening. I 
initially though that pulseaudio was meant to stop this from happening, 
however this is the first time I experienced sound skipping like this.

How do I disable pulseaudio  from loading at each login?
Any ideas?
