Bug description:
  [Impact]
  After CONFIG_SND_HDA_POWER_SAVE_DEFAULT is changed to 1, the codec runtime PM 
is
  enabled, on some codecs or for some hw design, there is noise with the codec
  runtime PM enabled.

  
  [Fix]
  put the machine in the power_save_black_list, this will set the power_save=0

  [Test Case]
  just boot up and do some audio operations, there is no noise anymore

  [Regression Risk]
  Low. this patch ony applies to the specific machines.


  
  I'm experiencing a repeating crackling noise after 19.04 upgrade that start 
just after the boot and before the login.

  I tried a bunch of fixes for pulseaudio I found googling, including this one 
https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches.2C_skips_or_crackling
   and this one 
https://askubuntu.com/questions/864608/audio-crackle-through-headphones. 
Neither of which helped.

  The command "killall pulseaudio" usually stop the noise for 10
  seconds, then the noise restart.

  The system was running smoothly on 18.10
