I guess you're referring to the mapping that is currently done via snd_jack_set_key() calls? If so, an additional sysfs or such interface would be handy, and it should be relatively easy. But a proper sysfs entry design is another question; it's an array, and this can be set for each jack object, so not that trivial. thanks, Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
