Thanks for the suggestion. I tried compiling both the stable versions
and the latest snapshots. The result was that new modules appeared in
/lib/modules/`uname -r`/updates/alsa, which I think is the idea.
However, when trying to use these modules, I received

$ sudo modprobe snd-hda-intel
FATAL: Error inserting snd_hda_intel
Unknown symbol in module, or unknown parameter (see dmesg)

And dmesg contains the following:
syslog:Jan 23 16:47:03 baldur kernel: [   23.389315] snd: Unknown
symbol unregister_sound_special (err 0)
syslog:Jan 23 16:47:03 baldur kernel: [   23.390067] snd: Unknown
symbol register_sound_special_device (err 0)

After reinstalling the alsa and linux-sound packages for Ubuntu, I
recovered sound, but I can't try the "test" parameter without being
able to load the module.

Do you know what this error means?
