The command
sudo hda-verb /dev/snd/hwC0D0 0x1a 0x707 0x05
works for me, but the patch proposed (I added the files), do not seem to
be working after reboots. Currently I have to run the command above
everytime I reboot.

Is it confirmed that this bug is fixed in newer Kernels? I am running 5.4.0.66
and have this problem in a Samsung laptop as well.
Thank you.

Hey, I own a Notebook 7 and was having the same problem with the
headphone jack (sound very low and distorted). I managed to solve based
on the solution at
https://bbs.archlinux.org/viewtopic.php?pid=1898849#p1898849. Basicaly,

An update: testing some more, I can confirm that there were improvements on
volume, now it is definetely louder: if it weren't the buzzing effect on the
sound, I could say it was fixed. On the other hand, the louder it gets the more
noticeable the distortion became.
Oh, and I noticed that
I sure did, running both new kernels didn't fix it.

That was the correct kernel to try for December 2019, but now 5.5 is
released so please try that :)

Updated the kernel to the 5.4 as suggested and it didn't make any
difference: sound through headphone jack still is low and heavily
distorted.

I don't know if my problem is related specifically to the Realtek AC256
codec. In any case, it seems FreeBSD folk fixed a while back the same
issue: no headphone output through some patches related to this codec on
some Dell models.

Just to give more insight about this, I just tried a live USB with
18.04.03 and the results are similar: the sound is extremely low, but
with no distortion whatsoever.

I can't get sound of my laptop (Samsung Notebook 7 Force) through the
headphone jack. The speakers work fine.
When I plug a headphone, I can hear the sound being played very faintly.
If I bump the volume to
Yes, I'm on a dual-boot setup.
I think it's also worth mentioning that I've tried Manjaro and
experienced the same problems.
