But I saw the widget has to be like a speaker, mic, lineout, etc. Could I use the snd_soc_dapm_enable_pin() to trigger any type of widget I want?  I tried to use it to trigger a supply widget, but I never see it works even I did snd_soc_dapm_sync() after the enable_pin.  Could someone provide some inputs?

Hi,

snd_soc_dapm_force_enable_pin is probably what you are looking for.
