Hi All,
I'm experiencing issues with a Lenovo P50 regarding headphones. It has
some similarities with the issue fixed in 5.8.13 with
commit ad0643252831ede7d6ab7b70a4f03768e032e6b4

ALSA: hda/realtek - Couldn't detect Mic if booting with headset plugged
I've been seeing this behavior since some time and now I'm running 5.8.14
Description: sometimes when I start the laptop with headphones plugged
in, no sound comes out of the headphones. The only thing I can hear is
the "usual" click when the kernel boots. Sound config in the gui
reports headphones plugged, nothing seems really wrong but no sound.
Removing headphones does not help: sound can be heard from laptop
loudspeakers but to get back the sound on headphones I have to unplug
the jack, reboot the laptop and once booted, inserting the headphones
makes everything work as expected. Gui tools report everything as
expected: headphones inserted, volume is ok and so on.
Below you can find the dmesg boot messages related to sound devices.
If you need more details please let me know.
If I picked the wrong address to report the issue please let me know,
I'll try to contact the relevant sources.
Please note that I'm not subscribed to this list even though I monitor
it, so being in CC: will be really appreciated.
Many thanks for any answer.

Hi Fabio,
Looks like the P50 has a different codec, it is alc298, and I don't have
the P50 to debug. It is better to report a bug to bugzilla against the
upstream kernel and cc the realtek engineers to take a look.
Regards,
Hui.

Thanks,
I opened a bugzilla entry here:
https://bugzilla.kernel.org/show_bug.cgi?id=209595
and CC'ed current realtek maintainer.
Many thanks for the suggestion.
