SRU Justification (and if that was needed for the Maverick one as well - 
the same applies there):

Impact: Playback and/or recording not working on several new Sony Vaios. 
Some report very faint sound, others no sound at all. I guess we get at 
least one bug a week for Lucid on these machines.

Fix: Add fixup verbs to send to the codec.

Testcase: We ask users to install the latest snapshot, they report back 
and it has fixed their problem.

Regression potential: very low as it only affects Sony Vaios with the 
ALC269 chip.

This Lucid version of the patch also piggybacks a fix for Dell Inspiron 
M101z, which is already in Maverick.
