The thread below discusses this issue and offers a workaround that worked for me. The problem is that when you upgrade, for some reason two kernels are installed a 386 kernel and generic. The sound problems are with the 386 kernel. Unfortunately, after booting into the 386 kernel, it generates the initramfs file for 386, but messes-up the generic kernel, so you can't boot into it anymore. (This is exactly what happened to me.) So you need to run: sudo update-initramfs -k 2.6.24-12-generic -c in the terminal, and reboot into generic. The sound worked there for me. Hope this works for you.
