If your CODEC driver is written to plug into ASoC framework, ASoC
dynamic audio power management(DAPM) will be able to link MIC-IN to
Lineout. After a set of ALSA mixer commands is issued to create a path
from one end point to another end point, DAPM will kick in and enable
the path according to widgets and audio routing map defined in the
CODEC driver.
