3657  * ordering in this list reflects vt1618 docs for Reg 60h and
3658  * the block diagram, DACs are as follows:
3659  *
3660  *        OUT_O -> Front,
3661  *	  OUT_1 -> Surround,
3662  *	  OUT_2 -> C/LFE

3665  * for all bitpatterns other than 00:
3666  *
3667  *        01       Unmixed Output
3668  *        10       Line In
3669  *        11       Mic  In
3670  *
3671  * Special Case of 00:
3672  *
3673  *        OUT_0    Mixed Output
3674  *        OUT_1    Reserved
3675  *        OUT_2    Reserved
3676  *
