Hui Wang,
After applying the patch to 4.20.4 (and even after removing hda-verb on
module load and wake-up from sleep / hibernation), there's no noise,
neither after boot nor after S3 sleep or hibernation. Yes!!!
The quiet sound still remains. After testing it again (mplayer,

Hui Wang,
Without the 0x12 line (but with the rest of your patch) there is no
noise.
Likewise, with your patch (standard kernel), running hda-verb or loading
the module with the equivalent options also stops the noise.
Additionally, with your full patch the sound is 10dB lower (or 20dB
lower bef
Hui Wang,
Apologies for the slow reply.
Do you mean that you also have quiet sound after the boot?
Today I upgraded to 4.19.12, and the results seem the same. I'm running
Funtoo Linux with "gentoo-sources" kernel, HDA and the Realtek codec as
modules and plain ALSA with no daemons. I tried to
Hui Wang,
Do you have a patch to set the values? I don't run Ubuntu. Is there a
publicly accessible branch with -proposed patches?
Thank you!

BTW, in case the sound card distinguishes between headphone out and line
out modes, thus may be relevant: my headphones have impedance of 70Ω.

Thank you!
Meanwhile I use modprobe to configure the "verb", but also run hda-verb
on wakeup from sleep or hibernation.

The two methods appear to do the same, except hda-verb applies the
change when run and the other method at the time the hda kernel module
is loaded. You can run hda-verb at boot instead, but the other method
looks cleaner to me, as it applies the fix when the hardware is
configured by the driver.
Hui Wang,
Yes, this solves the noise issue. Both the modprobe method from Lenovo
forum and the command you provided work perfectly. Thank you, and thank
you James!
I still have quiet sound initially. And, now that I compared it to the
kernel without the 0x12 line, it seems that the sound is qu
Plugging the headphones during Grub doesn't seem to matter.
thanks!

While waiting for your patch to reach the mainline, I just insert these

However, I still have issues with the sound.
