We need more than just the count handler - we need a complete list of everything that has been changed in the whole system. The graph walk itself is fine but we need to be able to do postprocessing of the delta that is generated. Like I said pre- and post- callbacks may well cover it. Note that this is specifically for ASoC, not ALSA in general.-- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
