[Aggarwal, Anuj] I tried to look into the soc-dapm.h for the appropriate platform/machine-domain specific widget which could do the needful but could not find any. What is the correct way of handling this? I want to pass the correct ramp value for my platform. > > -- > Péter _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
