Hi, That was built using the kernel sources provided by Ubuntu, through the package manager. For a config, you may also want to see if your kernel creates /proc/config.gz, which (should) also contain the config of the running kernel. You will need to be wary of which version of the kernel sources you install- they should match the running kernel EXACTLY without the need for any changing of version numbers. IF that still doesn't help, then please try obtaining the source tarball alsa-driver version 1.0.17 from alsa-project.org/ and building it- if you can successfully build it, then there may be another solution.
