No problem; according to the datasheet, this node does not have amp-out caps, and the driver has to read them from the default node instead. But this appears to work correctly, or you wouldn't have any control for this node. > As a more general question, how is the quirk for fixing the 0==mute > thing added?

(But it should be possible to make the "default" control device some new plugin that redirects to the "hw" device while changing some entries.) Regards, Clemens
