Just to document this for anyone else that might benefit, attached is
the final script I created. I reduced the previous list further from
788 to 358 verbs. There may be a few extra ones left, but probably not
many based on my testing, as removing more tends to lose one speaker or
not generate enough volume or other weird unexpected side effects. Its
definitely a long sequence of blocks of data that is critical as opposed
to one or two single statements. Anyway this smaller list appears to
achieve the original goal. If anyone ever wants to reduce further, the
data is broken into many blocks that look something like this (where the
row right after the one that ends with 0x23 appears to be most important
- so in this case its one of the 0x20 blocks):
sudo hda-verb /dev/snd/hwC0D0 0x20 0x500 0x26
sudo hda-verb /dev/snd/hwC0D0 0x20 0xc00 0x0
sudo hda-verb /dev/snd/hwC0D0 0x20 0x500 0x23
sudo hda-verb /dev/snd/hwC0D0 0x20 0x400 0x20
sudo hda-verb /dev/snd/hwC0D0 0x20 0x400 0x0
sudo hda-verb /dev/snd/hwC0D0 0x20 0x400 0xc0
sudo hda-verb /dev/snd/hwC0D0 0x20 0x4b0 0x11
Once you learn to work with the data as blocks it gets a lot easier to
sort.
Anyway, as far as what to do with this script....
I was not able to make a kernel patch that worked (maybe Mike can) and I
was not able to get early patching to work (which could be me because I
have never had any success with early patching). Originally I was just
running the script manually at boot, but I found that just creating a
simple systemd daemon does the trick (steps below). Now when I boot I
have full sound and it seems to last for a while. What was most
unexpected was that I also added back the single HDA verb for the
headphones (which I specifically tried and found did not work before as
a stand alone daemon) and now my headphones work along with the speakers
WITHOUT using the custom kernel patch that Mike created. Bizarre, but
whatever works.
Since my last script worked for PowerKiKi I feel confident this will
work for most Ion owners, but there is nothing in the script that is
truly specific to the Ion laptop. The Samsung Flex was released on the
same day and appears to have the same audio hardware, so likely this
works for flex users too. It may also work for pro or always users, I
am just not as sure on the hardware on those.
Steps to create daemon
1) Place the verb script in whatever location you prefer (it needs to
stay in one spot)
2) Make the permissions on the script file 777 and +x
3) Create a new daemon file named ....
/etc/systemd/system/ionsound.service
4) Place this text in your new daemon file
[Unit]
After=network.service
[Service]
ExecStart={full path to where you placed the file}/TO912.sh
[Install]
WantedBy=default.target
5) Update the daemon file permissions to 664
sudo chmod 664 /etc/systemd/system/ionsound.service
6) Activate the daemon
sudo systemctl daemon-reload
sudo systemctl enable ionsound.service
7) Reboot and you should have sound

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.)
