My sound doesn't work. I have ubuntu 9.04.
My lspci -v | less is:

00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
Subsystem: Santa Cruz Operation Device 1043
Flags: bus master, fast devsel, latency 0, IRQ 2299
Memory at fe9f4000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: HDA Intel
Kernel modules: snd-hda-intel

I installed a lot of packages and "pulse audio applet" to.

Any help?
