I understand. This should have been supported by simple-card since the beginning. When we tried to move all boards to use simple-card, we hit the wall by not being able to select and configure other sysclk_id than 0. I don't want to create yet another simple card which handles only sysclk_id 1 ;) On the other hand this ABI is backwards compatible since if it is missing it will default to the configuration we right now have regarding to sysclk_dir and sysclk_id. I will look at the CCF implementation for McASP first then for aic3x. -- Péter _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
