hm.... I added the function and the declaration to our 2.6.26 tree, compiling gives: sound/core/control.c: In function `snd_ctl_activate_id': sound/core/control.c:435: error: `control' undeclared (first use in this function) is it essential to use your devel tree? Harry PS: Liam: thanks for the offer, I am sure I will bug u with unqualified questions till the sound support on our Loox works as wanted (; And nice work on the 8750 codec! _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
