Have you eliminated  the possibility that the module options changed?

Updating the driver is pretty straightforward, but what you have to do depends 
on what your options are. By that I mean your distro should have sources to 
build a package. It saves a little bit of aggravation over upgrading from 
tarball (not much, but some).

In a nutshell, you turn off everything under Sound in the kernel cfg except 
the very top level module, then build/install the ALSA drivers from the 
not-the-kernel-sources. Once thats done you have to configure the module 
loading and init script for the specifics.
