I modified the last line in /etc/modprobe.d/alsa-base.conf with the text below and rebooted ( added options: model=6stack-dig and position_fix=1 ):
options snd-hda-intel power_save=10 power_save_controller=N position_fix=1 model=6stack-dig
I also removed the /home/myusername/.pulse* directories but I don't know if that made any difference.
I found something that seems to help.

$ lspci |grep Audio

$ cat /proc/asound/ card0/codec# * |grep Codec
Codec: Realtek ALC1200
$ aplay -l

So now the "crunchiness" has gone away, and the sound doesn't go to mute everytime I reboot and log back in.
