+/* VIA VT1618 8 CHANNEL AC97 CODEC
+ *
+ * VIA implements 'Smart 5.1' completely differently on the 1618 than
+ * it does on the 1617a. awesome! They seem to have sourced this
+ * particular revision of the technology from somebody else, it's
+ * called Universal Audio Jack and it shows up on some other folk's chips
+ * as well.
+ *
+ * ordering in this list reflects vt1618 docs for Reg 60h and
+ * the block diagram, DACs are as follows:
+ *
+ *        OUT_O -> Front,
+ *        OUT_1 -> Surround,
+ *        OUT_2 -> C/LFE
+ *
+ * Unlike the 1617a, each OUT has a consistent set of mappings
+ * for all bitpatterns other than 00:
+ *
+ *        01       Unmixed Output
+ *        10       Line In
+ *        11       Mic  In
+ *
+ * Special Case of 00:
+ *
+ *        OUT_0    Mixed Output
+ *        OUT_1    Reserved
+ *        OUT_2    Reserved
+ *
+ * I have no idea what the hell Reserved does, but on an MSI
+ * CN700T, i have to set it to get 5.1 output - YMMV, bad
+ * shit may happen.
+ *
+ * If other chips use Universal Audio Jack, then this code might be applicable
+ * to them.
