+ * called Universal Audio Jack and it shows up on some other folk's chips

+ *
+ * ordering in this list reflects vt1618 docs for Reg 60h and

+ *
+ * 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
