Weird jack detection on ASRock B450M Pro4

[Arun Raghavan]

Hi folks,
I ran into some weird behaviour on this motherboard. First, alsa-info is here: http://alsa-project.org/db/?f=f48105f391d848b34b3779f27369130ca024f417

The weird behaviour is that the HDA card is picked up fine, but jack detection is broken on boot. However, this gets "fixed" after you run alsa-info. The before/after codec info is at:

The key delta is:

Any thoughts on what's changing that, and how this should be fixed?
