OK, then it's indeed so.  Interesting that the pincfg is identical
with the *modified* preset.

Hm... is it from hg.alsa-project.org?

The newest changeset is:

Check "hg log" whether it matches.

Then this is at least no regression.  A good thing (let's think
positively :)

Seriously, another missing thing can be either EAPD on this widget or
EAPD via GPIO.
In the former case, the patch like below might fix.
In the latter case, you'd need to add the following line appropriately
in patch_stac922x():

	spec->gpio_mask = spec->gpio_data = 0x01;

The value 0x01 can vary depending on the machine implementation.  Try
different values if the above doesn't work.
