Yes, I only changed that option, the other options are by default . And
yes, in my case, the noise dissapeared completely.

Title:
  HP Notebook Probook 440 G3  HDA Intel PCH horrible sounds while
  booting

Status in alsa-driver package in Ubuntu:
  Confirmed
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  At first there was no native recognition of my sound driver (see this [ https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1525554 ] a lot of others a experiencing this problem)
  so there was a workaround to fix that, the notebook has sound output now, but ever since i got these horrible scratching noises while booting, which i dont have booting windows, which is kinda surprising while one could take it for a bios or hardware problem.

  basic workaround for fixing missing sound driver was adding two lines to the /etc/modprobe.d/alsa-base.conf
  options snd-hda-intel single_cmd=1
  options snd-hda-intel probe_mask=1

  with these lines a was able to get sound, but i then have these crazy
  noises while booting.

  the following are some lines from the terminal which might help:

  'lsb_release -rd'

  even adding the right driver and module into /etc/modules (like snd-
  hda-intel model=PCH index=0) did not work, like i found in this thread
  ( https://wiki.ubuntuusers.de/Soundkarten_konfigurieren/ ) sorry for
  the german thread.

  i dont know what to add anymore. feel free to ask.
