Same approach is used in h1940 and magician. What I'm trying to figure out is if the GPIO is wired directly to the UDA1380 or if this is controlling something external to the UDA1380 which these designs just happen to have copied. If it's a direct connection to the UDA1380 then using GPIOs directly is perfectly sensible. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
