Jack state is already exposed via the input layer by the ALSA jack core. Reporting of GPIO state via gpio_export() would be additional to that and would be purely for debug purposes, it would not be recommended for use by userspace applications. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
