In both outputs, there is no change in "Headphone Jack" control value.
It means that  the driver didn't detect the headphone jack.  Most likely it's
either a hardware problem or a BIOS problem.

The fact that the old PA worked was a bug.  It shouldn't have worked as you
expected.  Now it gets fixed, and the problem is revealed.

That said, it's no regression but rather a "fix" to behavior correctly to the
hardware that doesn't behave as expected.

This implies the same consequence.

Now, what you can do is to check the real pin configuration and the hardware
configuration.  Try to alsa-tools package (or hdajackretask) and see which any
pin gives the jack detection corresponds to your headphone jack.  If yes, you
need to reassign the headphone pin correctly, set up as a "patch" firmware to
load to the driver.

If no pin reacts to the headphone jack, it's a hardware problem.  You might
have connected the front panel in a wrong mode (AC97) that has a different pin
assignment.
