The 12.04 package failed to install for me (in Precise):

In file included from /var/lib/dkms/alsa-hda/0.1/build/patch_analog.c:29:0:
/var/lib/dkms/alsa-hda/0.1/build/hda_codec.h:48:8: virhe: redeclaration of enumerator ”SND_PR_ALWAYS”

I’m guessing this is because I’m running linux-signed-generic-lts-quantal which is 3.5.0.22.29 currently; the 12.10 package seemed to install fine. Will testing data from this kind of hybrid setup still be useful?
