Can you clarify: are you saying that installing that oem-dmic-sof-
lp1825294 package is going to be the permanent solution to this problem,
or that you're asking us to test if that package solves the problem
before the change is incorporated into the official Ubuntu kernel?

Title:
  volume control doesn't work (it's just on/off) on Lenovo ThinkPad X1
  Carbon 7th gen

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  On my Lenovo ThinkPad X1 Carbon 7th generation using the built-in
  speakers, the volume is either off or on, there's no gradation in
  volume when I move the slider up or down.

  If I enable Over-Amplification than there's gradation in volume when I
  turn the volume up past 100%, but not for 0-100%.

  This problem does not occur with a headset plugged into the 3.5mm
  jack.
