The driver has no "PCM" volume. It's a volume for softvol plugin,
which is used for the "default" PCM. If you access the hardware
directly via hw layer, it's ignored.

Interesting. Could you once stop/close the capture stream and
restart recording again when you plug the external mic? Does the same
Actually there is no mixer in this route. The portc_automic
reprograms the ADC stream tag on the fly if the stream is in use. So,
this might give a strange effect.
