Lenovo B50-70 fits the description.

$ arecord -l 
**** List of CAPTURE Hardware Devices ****
card 1: PCH [HDA Intel PCH], device 0: ALC233 Analog [ALC233 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0


I'm on Arch Linux and have tried adding "options snd-hda-intel model=inv-dmic" 
in either modprobe.conf or snd-hda-intel.conf but doesn't fix the problem - I 
think I'm almost there but don't fully understand what to set.

Muting one of the channels while boosting the other works every timw,
just like in the description. Problem is, some apps (such as Facebook
messenger video call) adjust the volumes on their own and they link left
with right.

How to proceed and what info do you need, thanks!
