OOI which device? I'm not sure what you mean by guidance here. The standard thing would be to do it as a regular CODEC driver with a custom interface for userspace (eg, gstreamer) to talk to. The best way of handling DAPM will depend on implementation but probably representing the output of the DSP as an input pin will be easiest. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
