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
