This should all be one ASoC device, especially given that the fact that all the paths use the TWL4030 somehow. Have a look at how, eg, the neo1973 driver handles the bluetooth. For now there's not *particularly* sane support for multiple codecs. Does the DAC have any software control? If not it should be fairly straightforward to handle. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
