[alsa-devel] question on static dapm routes

Hi Mark,

In the codec file which we are trying to write, we do not have any dynamic Switching paths. So for the structure snd_soc_dapm_route, its always {sink, NULL, source}. The DAPM widgets are getting enabled at the codec probe (as we saw that they are getting declared as static) . So this consumes power and we want them do be turned on only when DAI is started?

So, does that mean that for every stream, we make use of the startup and shutdown functions to do our power management of the widgets. Or is there a way ASOC automatically takes care of powering of the static paths as well?

Thanks, Harsha
