A few things since I last posted:
After having done the below command...
`amixer -c 1 cset numid=3,name='Speaker Force Firmware Load' 1`
Every subsequent reboot the audio never broke. I had multiple 2+ hour
sessions with no issue.
I never re-ran the above command.
Adjusting the volume would have a noticeable 'delay' (around 0.5
seconds to 3 seconds) before the audio mixer related GUI would
respond.
As a test I did a fresh install of endeavour-os (on kernel 6.8.7) and
sure enough, the issue is back and I can break the audio in less than
5 minutes of use.

not working
Unfortunately, the result of the below command are as follows once audio breaks:
$ su root
# rmmod snd_hda_scodec_tas2781_i2c
# i2cset -y 3 0x70 0x00 0x00
Error: Write failed
# i2cset -y 3 0x70 0x00 0x00
Error: Write failed
# i2cset -y 3 0x70 0x7f 0x00
Error: Write failed
# i2cdump -y 3 0x70

After modprobe snd_hda_scodec_tas2781_i2c is run, audio actually works
again, for a few minutes.
I will note I get the same result above even if I do it while audio
works, so if I'm doing something wrong please let me know.
For testing purposes, if I want to enable/disable your workaround
solution, would changing the 1 at the end to 0 be sufficient?
`amixer -c 1 cset numid=3,name='Speaker Force Firmware Load' 1` ->
`amixer -c 1 cset numid=3,name='Speaker Force Firmware Load' 0`
