Is this still "N/A" when you try again?
Yeah, I've run the script a few times and this has always been N/A.
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? Is it a kernel patch or some tweak in the /usr/share/alsa/ tree (i.e. alsalib based quirk?)
At the moment, no working mechanism for changing control information in user space exists. (But it should be possible to make the "default" control device some new plugin that redirects to the "hw" device while changing some entries.)
