Test, with 'audacious' playing in background, and no headphones:

	# First mute; wait a sec; then unmute.
	% for STATE in Enabled Disabled ; do amixer -c0 set "Auto-Mute Mode" $STATE ; sleep 1s ; done

Result:  the music goes off for one second (as per "sleep 1s" above);
i.e. the speakers mute for 1 sec, then go back on.

Another test with the headphones plugged in (during which the speaker
is always off): the headphones mute for 1 sec, then go back on.

Seems like this bug's flown, but more tests are needed, I'll try to run
'em.

Thanks for the careful feedback, and HTH...
