Yes, but it alone doesn't help for analysis because it's already an
abstracted mixer element.  We need to figure out which pin corresponds
to the speaker output.  It must be either 0x0f or 0x11.

BTW, any reason to set the "Speaker" volume so low?  It's almost
inaudible.  Raise this volume.

If raising volume doesn't change, and if you can still run the older
kernel, try to change the pin control via hda-verb like:
	# hda-verb /dev/snd/hwC0D0 0x0f SET_PIN_WID 0x00
and check whether the speaker still works.  If 0x0f doesn't change,
try 0x11,
	# hda-verb /dev/snd/hwC0D0 0x11 SET_PIN_WID 0x00

If the pin 0x0f actually changes the speaker output, use the patch
below instead of the previous one.

This is correct.  When there are only internal and external mics,
the driver enables the auto-mic switching mode.

Just plugging the mic jack should switch to the external mic
automatically just like the headphone/speaker switch.
