3.5 mm jack headphones not detected when plugged in

I have an interesting problem when I plug in my 3.5 mm headphone jack into my laptop.  The headphones are not detected and when I force the switch on with `pavucontrol`, it lists it as Headphones (unplugged).  I get a sound when I change volume.  I have to change the audio backend on Strawberry to 'Plays audio to a pulse audio server' and explicitly choose the device and then it works there.  However, in Firefox and mpv, the sound is dead.

The audio device in question is:  Realtek ALC245.  Apparently, it's known to have this exact issue, but there aren't any elegant solutions that I can find.

`qpwgraph` doesn't ever show the headphones, either.

I should mention that my speakers and bluetooth headphones work great.  Any 2.5 mm jacked headphones I have, however, do not.  And, yes, all of my studio monitor headphone work on all other Linux machines, as well as on analogue  audio devices.

I have the following programs installed:

pipewire-pulse
pipewire-jack
pipewire-alsa
pipewire-session-manager
pipewire-audio
wireplumber
alsa-utils
alsa-firmware
pavucontrol

Any help to this baffling situation would be welcome, as always.

Edit:  I just discovered that it works only under the `Pro Audio` profile.  I have no idea why this and not the others.
