Did you mean when it worked?  Was it before moving to the generic
parser, or after it but before upgrading to the latest tree?
In the latter case, try git bisection to figure out the culprit.

But, it's anyway better to update the git branch.  You are testing the
too old version (there have been already 75 commits after your testing
one).

OK, so the unsol event is generated properly.

Is the alsa-info.sh output you attached previously at the state after
unplugging?  If so, I see no problem in the code register.  The path
0x04 -> 0x29 -> 0x12 looks fine, all unmuted, power D0 and the pin set
properly.

If something doesn't work as expected, we need two alsa-info outputs
for comparison: the working one and non-working one.
