The driver is responsible for things that apply over the entire platform - for most platforms this is DMA since the DMA control is the same for all the different audio interfaces the platform has. This is nothing to do with creating a card, that is initiated by the machine driver. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
