It might be. It is important not to mix VT1708 and VT1708S. For VT1708S,
the following DACs are used in code:
/* config dac list */
switch (i) {
case AUTO_SEQ_FRONT:
spec->multiout.dac_nids[i] = 0x10;
break;
case AUTO_SEQ_CENLFE:
spec->multiout.dac_nids[i] = 0x24;
break;
case AUTO_SEQ_SURROUND:
spec->multiout.dac_nids[i] = 0x11;
break;
case AUTO_SEQ_SIDE:
spec->multiout.dac_nids[i] = 0x25;
break;
}
So 0x12 is not used for any of the surround outputs.
