Ubuntu High Quality Sound - Updated for Ubuntu 20.04

ubuntu_high_quality_sound.txt

It seems that the audio can be in a broken state if one is using dual boot with Windows and somehow Windows has changed the power
state of the audio card causing the audio issues, even after all the configuration done in Linux. Solution is if it break after 
booting to Windows and back to Ubuntu, is shutting down the computer, reboot doesn't work.
