Title:
  sound not working in 4.15.0-58, but does in 4.15.0-55

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  First excuse me, this is my very first bug report, if anything is
  missing, notify me on email.

  ----------

  I find it rather hard to believe, but since I installed kernel:

  > 4.15.0-**58**

  several days ago, my sound on Linux Mint 19.2 Cinnamon stopped
  working, and no matter what I tried like:

      sudo apt reinstall alsa-base pulseaudio
      sudo alsa force-reload

  +

      reboot(-s)

  +

      alsamixer

  nothing brought me sound back, so I just installed an older kernel,
  namely the littlest bit older one:

  > 4.15.0-**55**

  now everything works like a charm.

  -------

  How can I debug this and figure out if the problem is a bug in the
  kernel itself or in some other audio-related package? I don't know
  what exact information you could require for this.

  -------

  I have just reproduced the problem by upgrading back to 4.15.0-**58**
  from 4.15.0-**55**. Sound not working again. Plus, by switching to an
  older kernel proves sound is functional.

  -------

  Hardware:

  laptop Dell HG6D142: [direct link to product page][1]

  ----------

  $ lsb_release -rd
  Description:  Linux Mint 19.2 Tina
  Release:      19.2

  
  -----------

  expectation: sound working

  -------

  happened: sound does not work at all, neither with Intel GPU, nor
  Nvidia GPU online, tried all I could mentioned above

  
  --------

  I attach a simple diff between 55 and 58 loaded.

  -------

  Thank you!
