OK, had some small struggles with grub on efi, but yes, once I made a
completely new kernel version with just this patch then it did work and
does survive reboots and source changes, etc. So at least until a new
kernel comes out I am set :)
Is there anything I can do to help with the

a difference?
The fact that you were able to apply the patch and compile makes me
think that a checkout of v5.8 would not make a difference.
Can you try this patch instead? (See attached)

OK, so :
- downloaded kernel source
- applied patch
- ran make to create new debs
- activated new custom kernel
- added "options snd-hda-intel model=alc298-samsung-headphone" to
alsa-base.conf
- rebooted
- used "uname -r" to ensure the new custom kernel was
Yea, sorry. I was working off an apt-get version of the kernel source, then
after posting, I noticed you were using git. I have downloaded from the source
from git and applied the patch successfully. The new custom kernel is now in
the make process. I will update once it finishes and I can

This works for me

OK, While I would prefer to wait until the patch lands, for an ubuntu LTS that
can take a while, so I tried to do it manually. I downloaded the kernel src,
but I am having trouble applying the patch. I am using the command :
patch -i ~/Desktop/0001-ALSA-hda-realtek-Add-model-alc298-samsung-

@John Hoff
Darn. Let's try something else.
I submitted a kernel patch adding model=alc298-samsung-headphone (see
attached). It exposes the quirk that fixed my Samsung Notebook 9 Pro as
a "model" option that you can pass to snd_hda_intel. Give it a try:
1) Apply my patch to the linux kernel,
@gannon1
Sure. I tried just that single character change first. No change after
reboot, i.e. still had to issue the manual command. If I use the manual
command with either 0x5 or 0xc5 it works perfectly in both cases. Just
for good measure I also tried adding back the model section too, but
@John Hoff Looks good to me. Can you try again after changing

0x1a 0x707 0xc5
to

0x1a 0x707 0x5
The latter should be identical to your hda-verb command (0x707 is the
encoding for SET_PIN_WIDGET_CONTROL) except that Early Patching modifies
the hda configuration BEFORE initializing
@gannon1 Thanks for the reply. Perhaps I am missing something because
it seems like it should work, but I have not had any luck with the
method described by ironincoder. Just to be sure I did it again from
the start using the following steps (perhaps I just didn't understand
and missed a
@PowerKiKi @John Hoff Does Early Patching as described above by
ironincoder fix the problem?
If it does, and you post your alsa_info.sh output, I can submit a kernel
patch for you. I did so just now for a user named terrydrever who has a
Samsung Galaxy Flex Book (NT950QCG-X716) and confirmed that
I have the 13 inch Ion with the intel built in gpu. I am also running standard
Ubuntu and not Xbuntu. I have never had the system lock up or freeze on any
occasion and I use it for at least 10 hours a day. My keyboard lights have
also always worked perfectly from the start. In fact, the
linux-headers-5.8.1-050801_5.8.1-050801.202008111432 and booting with
secure boot disabled will not anything. Still no sound, and the command
workaround still works.
On a side note, the built-in mic does work as expected. So I use
bluetooth headphones for listening and built-in mic for speaking.
I can confirm that after installing the package `alsa-tools`, then the
following command will restore sound on headphones instantaneously:
sudo hda-verb /dev/snd/hwC0D0 0x1a SET_PIN_WIDGET_CONTROL 0x5
In the meantime I did try a newer kernel, linux-
I have the same computer and issue as PowerKiKi... the new Samsung Ion running
ubuntu 20.04.
I have found that I can make the headset jack work temporarily if I
issue this command :
sudo hda-verb /dev/snd/hwC0D0 0x1a SET_PIN_WIDGET_CONTROL 0x5
But it only lasts until the sound subsystem goes
I just installed a fresh Xubuntu 20.04 (Linux 5.4.0-42-generic) on my
brand new Samsung Galaxy Book Ion NT950XCJ-X716A. And of course I do
experience the issues described here: very low volume on headphones and
no sound on speakers.
In pavucontrol, under "Output devices", I see 3 HDMI outputs,
I'm experiencing this bug on my laptop Samsung Notebook Pen S AKA
Notebook 9 Pen 2019 Edition.
I fixed the headphone problem by using Early Patching in bugzila [1].
But my laptop's Subsystem Id is 0x144dc812, and this is different from
above.
Can you add my laptop vendor on kernel?

Good news! A very smart Arch user by the name of ronincoder discovered a
fix for the headphone jack. I worked with ronincoder to make a kernel
patch [1] and our patch made it into the 5.7 kernel release! It was also
applied to the 5.4 LTS kernel. I booted both 5.7.2 and 5.4.46 and the
