Changing the "Auto-Mute" control does not do anything; the system always
exhibits Automute behavior (if that's a bug, it's one which I did not

With your patch, I get a system which still has two issues
that were not there in 3.17:
 - the "Headphone" control is present but has no volume bar
 - the "PCM" control does not affect the Speaker volume
