Yeah, part of what I was driving at was that it would be good if we could handle standard conforming AC97 systems by having a fabric/machine driver which provides the required glue to connect up whatever codecs it was able to probe on the bus to the controller. Having such a driver would mean that with ASoC support for their AC97 controller platforms would only have to have a mechanism to decide to use the generic driver to also get support for standard AC97 subsystems. This would leave these systems using an ASoC machine driver but not one that is custom to any given system. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
