It seems the snd_hda_intel module has a vast array of options that one needs to sort through in order to get quality sound output. It might be nice to have a robust "detection" scheme to set these options out of the box if a board is detected that needs additional options to work better.
I was hoping that this would be a 100% acceptable workaround, but I still hear some of the "crackling" from my speakers that caused me to work around the issue by (in previous Ubuntu releases) adjusting the PCM volume down.
Note, I found that adding the following file to my system helps SOME of the problem:
$ cat /etc/modprobe. d/sound. conf
options snd_hda_intel model=hp
