Hi Drew,
Since creating the TO912.sh script I have also upgraded to a GalaxyBook2
Pro (NP930XED) running 22.04 and the script was required (i.e. the
latest kernels don't automatically fix issue), but the script continues
to work fine for me on both headphones are speakers. Personally I would
recommend upgrading from the 5.15 kernel because it doesn't work fully
with the intel grpahics (im running 6.0.6-060006-generic now), but that
is unrelated. Here are the full steps I did again that work for me ...
I still have not figured out how to make the screen brightness control
functional on the book 2 pro, but also a different story...
- placed TO912.sh script and set as 777 +x
- Create daemon for boot
sudo gedit /etc/systemd/system/ionsound.service
Add text in file
[Unit]
Description=Custom Sound
[Service]
Type=idle
ExecStart={enter your path to script}/TO912.sh
[Install]
WantedBy=multi-user.target
sudo chmod 664 /etc/systemd/system/ionsound.service
- Create daemon for sleep exit
sudo gedit /etc/systemd/system/ionsoundsleep.service
Add text in file
[Unit]
Description=Custom Sound Sleep Fix
[Service]
Type=idle
ExecStart={enter your path to script}/TO912.sh
[Install]
WantedBy=suspend.target
sudo chmod 664 /etc/systemd/system/ionsoundsleep.service
- Activate daemons
sudo systemctl daemon-reload
sudo systemctl enable ionsound.service
sudo systemctl enable ionsoundsleep.service
Note, I left the names as Ion because I was too lazy to change, but
nothing in here is ion specific and this does work on your model. You
can change naming if you like as long as you change it everywhere...
For the kernel part, if you haven't already discovered the mainline tool for
kernel mgmt then I would highly recommend trying it....
sudo add-apt-repository ppa:cappelikan/ppa -y
sudo apt install mainline -y
Launch mainline GUI and pick kernel to install

Title:
[950SBE/951SBE, Realtek ALC298, Speaker, Internal] No sound on
internal speakers, very very quiet on headphones
Status in Linux:
New
Status in linux package in Ubuntu:
Fix Released
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:
