           Say Y here to include support for sound cards based on the
           Asus AV66/AV100/AV200 chips, i.e., Xonar D1, DX, D2, D2X, DS,
           Essence ST (Deluxe), and Essence STX.
-          Support for the HDAV1.3 (Deluxe) is experimental; for the

           To compile this driver as a module, choose M here: the module
           will be called snd-virtuoso.
