@gannon1 @PowerKiKi

Mike, I never heard back from Jaroslav (I suspect he is pretty busy),
and my consulting work is very slow with the pandemic so I just
continued to work on it.  Your concept is spot on.  Thank you for all
the wisdom and thoughtful guidance.  I am happy to report, after much
more effort than I care to admit, that step 1 has been successfully
achieved and I have stereo sound through my laptop speakers... finally!
Once you get through all the numerous setup pitfalls, it seems (a bit of
an assumption on my part) like the big gotcha is that the windows driver
appears to instantaneously turn off the speakers when not in use (i.e.
if you record a large time period like booting or disabling and enabling
devices then the speakers start and end in off mode and you never catch
it).  It took numerous attempts to catch the right segments.

Anyway, I have begun working on step 2 now.   I stared with >2000 verbs
and am down to what seems to be a consistent 788.  I am confident there
are more to eliminate because it turns on the left speaker (alone) then
turns on the right speaker (alone), then (most importantly) ends with
stereo.  For at least the galaxy book ion (likely will work for others
too), I should be able to provide an optimized result soonish.

PowerKiKi, even with the Xbuntu difference, I feel confident what I have
now will at least work for you since you have the same Ion hardware.
The sound is actually pretty good on these laptops (I never heard it
before today because I wiped windows on day 1 :)....  If you would like
to give it a shot, just run the attached script.  I use it on top of
running a custom kernel that includes Mike's headphone patch and I have
full sound on speakers and headphones during the entire session.  Once I
minimize the verbs I will try creating a custom kernel with the final
verbs (I have skipped that for now because the hda verbs work fine and
each attempt at a custom kernel is about an hour journey..)

Title:
  [950SBE/951SBE, Realtek ALC298, Speaker, Internal] No sound on
  internal speakers, very very quiet on headphones

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I've been googling this issue for 10's of hours and tried many things.

  Relase of Ubuntu: 19.10

  Expected outcome: Music plays on the internal speakers and headphones.

  Actual outcome: I can barely hear audio using headphones with volume
  turned up to 150%.  Absolutely nothing comes out of the speakers. (The
  speakers sound great under Windows 10.)

  Complete alsa-info output is attached, but here are some snippets:
