No sound from speakers, but headphone ok

I just upgraded ubuntu from 9.04 to 9.10. I hate upgrading, I like a clean install. In any case, the speakers sound stopped working, while headphones work!

After some investigation, left over pulse audio config files where causing problems, a fix is to remove them

cd
rm -rf .pulse*

tada! done works nicely
