The question is rather how to generalize the communication. One idea is to split the current driver into a generic HD-audio bus driver, controller driver and codec drivers. In that way, you'll get a safer access. But this would be a major rewrite, and no trivial task, although it's a good and clean direction to go. thanks, Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
