For audio and voice interface, following things need to be configured: Audio interface: - Output pins state: high impendance or application mode - Enable audio interface Voice interface: - Enable voice data input - Enable voice data output - Output pins state: high impedance or application mode - Enable voice interface I think that interfaces can be enabled in DAI init as Mark suggests, but input/output should be enabled depending on whether we are doing playback/capture or not, and then they should be handled in the codec driver. For the codec operation mode selection, I still think Peter's advice is more appropriate because options1,2 are not really tight to DAIs. For example, we can be in option2 (voice/audio) and do transferences using both DAIs: I2S and PCM. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
