NB: ignore_ctl_error=1 may help when you get an error at accessing
the mixer element such as URB error -22. This happens on some
buggy USB device or the controller.
+ NB: quirk_alias option is provided only for testing / development.
+ If you want to have a proper support, contact to upstream for
+ adding the matching quirk in the driver code statically.
