Same problem. Sound worked in Gutsy. Upgraded from gutsy to Hardy and got no
sound. Upgraded from Hardy to Intrepid still no sound
This is a Acer Ferrari 5000 laptop.
Why does Ubuntu have so many regressions? It seems like every time a
new version comes out something that used to work gets broken. I think
the quality of Ubuntu is starting to suffer. I never saw this problem
on Mandrake back in the day. With Intrepid Atheros wireless on another
laptop quit working and now this sb4x0 issue on this laptop.
