Fantastic, this indeed gets my sound working on 2.6.37-rc1.

I just noticed this in the changelog of 2.6.37-rc1 [1]:

    ALSA: hda - Apply ALC269 VAIO fix-up to all Sony laptops with ALC269

    We've applied a fix-up for ALC269 VAIO only for two models.  But all
    Sony VAIO models with ALC269 codec seem to require the similar fix.
    Let's apply it with vendor-id mask.

I suppose this must be the culprit.  Should I email Takashi to let him know
that there might be a problem with this patch?

In related news, 2.6.37-rc2 was just made available.  It contains another
patch for us Z users, relating to i8042 and keyboard/touchpad getting messed
up.  *shrug*
