Do the driver need a pin fixup for the digital pin or more check when
assign dig out type ?

If codec has two digital pin complex with diffferent type, check whether
the primary digital pin complex support DETECT

case AC_JACK_SPDIF_OUT:
case AC_JACK_DIG_OTHER_OUT:
if (cfg->dig_outs >= ARRAY_SIZE(cfg->dig_out_pins)) {
codec_info(codec,
   "ignore pin 0x%x, too many assigned pins\n",
   nid);
continue;
}
cfg->dig_out_pins[cfg->dig_outs] = nid;
cfg->dig_out_type[cfg->dig_outs] =
(loc == AC_JACK_LOC_HDMI) ?
HDA_PCM_TYPE_HDMI : HDA_PCM_TYPE_SPDIF;
cfg->dig_outs++;
+        if (cfg->dig_outs == 2)
+             if (cfg->dig_out_type[0] != cfg->dig_out_type[1])
+                  if (! snd_hda_query_pin_caps(codec,
cfg->dig_out_pins[0]) & AC_PINCAP_PRES_DETECT))
+                        cfg-> dig_out_type[0] = HDA_PCM_TYPE_SPDIF;

break;
