Hi; I am sorry for the vagueness of the questions, but now that i have some understanding of how these files are supposed to work i want to get this right! to support 4.0/5.1/7.1 for the vt1618 codec i have to change a different set of twiddlers than what is called out in the current version of the conf file. worse yet, the twiddlers called out in the current file dont even *exist* on the vt1618: { name "Surround Down Mix" preserve true value off lock true optional true } { name "Center/LFE Down Mix" preserve true value off lock true optional true } How do i add new stuff without breaking old stuff? is there a sub-identity that i could use? tnx! johnu _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
