I have tried a few attempts but it's pretty confusing.

These ones don't do anything:

# hda-verb /dev/snd/hwC1D0  GET_PIN_SENSE
# hda-verb /dev/snd/hwC1D0  0x0 GET_PIN_SENSE


I don't know what to make of this output:

# hda-verb /dev/snd/hwC1D0  0x0 GET_PIN_SENSE PIN_CAP
nid = 0x0, verb = 0xf09, param = 0xc
value = 0x0
# hda-verb /dev/snd/hwC0D0  0x0 GET_PIN_SENSE PIN_CAP
nid = 0x0, verb = 0xf09, param = 0xc
value = 0x0
# hda-verb /dev/snd/hwC0D0  0x16 GET_PIN_SENSE PIN_CAP
nid = 0x16, verb = 0xf09, param = 0xc
value = 0xffffffff
# hda-verb /dev/snd/hwC0D0  0x19 GET_PIN_SENSE PIN_CAP
nid = 0x19, verb = 0xf09, param = 0xc
value = 0xffffffff
# hda-verb /dev/snd/hwC0D0  0x1a GET_PIN_SENSE PIN_CAP
nid = 0x1a, verb = 0xf09, param = 0xc
value = 0xffffffff
# hda-verb /dev/snd/hwC0D0  0x1b GET_PIN_SENSE PIN_CAP
nid = 0x1b, verb = 0xf09, param = 0xc
value = 0xffffffff

I have tried both options.

After rebooting with the apply option set I don't hear any static or audio
with the PA test app.

I have checked alsamixer again after the last round of tinkering with
hdajackretask and" Speaker CLFE" is now showing up but it does not have
volume control just mute on/off.

I see the following new controls

Speaker CFLE (mute only)
Speaker Front (mute + vol)
Speaker Side (mute only)
Speaker Surround (mute + vol)

I have tried several combinations with hdajackretask

I am not able to get audio out of the physical rear speakers or sonic
master output.

I can get audio to play back in the front l/c/r speakers with varying
combinations.

ex.

7.1 side l/r plays through front l/r or front c
4.0 rear r/l plays through front l/r
2.1 l/r plays through front l/r
2.1 subwoofer plays white noise through front c

Most of the time it is only front left/right that make any sound.
Sometimes there is no sound on one audio profile but it works on a couple
of channels on another profile.

Any time that the Center LFE works it produces white noise.

I have tried with both options: apply and patch/reboot

I can keep playing around with the settings until I eventually stumble on
a combination that works but it seems like this process should be
scriptable. Given that I will probably spend hours of my time on the test
process and I have already spent 4 separate sessions on testing it seems
like it would be better value for my time and others going forward to
write a test script.

So what do I need to do to write a script that will test all the
combinations and play audio through them? Or am I missing something that
someone else has already written for this purpose?

Currently I am using this process:

1: hdajackretask - modify params
2: pulseaudio -k
3: hdajackretask : apply settings
4: pulseaudio -D
5: open PA audio config
6: select audio output option and press test speakers button
7: manually press every button

Rinse and repeat.

Surely there is a more humane method for testing the variations ;-)
