[20ENCTO1WW, Realtek ALC298, Speaker, Internal] No sound at all

[Byron]

I have a Lenovo P50 with the docking station. When the laptop is plugged into the docking station sound will not play out the external port.

An lspci -n gives me:

00:1f.3 Audio device [0403]: Intel Corporation Sunrise Point-H HD Audio [8086:a170] (rev 31)

I have updated the bios.

Status changed to 'Confirmed' because the bug affects multiple users.

Recent updates seem to have made it worse.
1. Docking station's headphones remain as was: It does not even detect it.
2. Docking station's microphone is detected in alsa-mixer.
3. Headphones on PC jack get no output ! In all controls, sound seem to go there correctly, but the actual headphones receive no sound. It comes after adding "options snd-hda-intel model=laptop-amic", but then do work the lights for mute.
4. Microphone on PC jack works fine.

I also use brand new Lenovo P50 and there is no sound at all (I don't use docking station).

I am using Samsung PenS 930SBE. It has ALC298 card and no sound.

I tried to compile alsa daily, then only on headphones there are some beeps.
