I guess those patches are ok since those connections are also unmuted in my
10 channels ad1988a

As alc892 datasheet is available at realtek web site , no need to use
codecgraph, just look at the Block diagram and you will able to find out
those inputs pins (e.g. Front Mic, Rear Mic ,... ) connected through 0x0b to
those output pins

 Is it correct to set spec->multiout.hp_nid = 0 or
spec->multiout.no_share_stream in order to disable the multiout to use hp

and use alt_dac_nid and stream_analog_alt_playback to enable Front Panel HP
playback (multistream playback) like those intel desktop videos ?

This assign headphone and mic at front panel to alt_playback and alt_capture

    if (!spec->cap_mixer)

+    if (codec->vendor_id == 0x10ec0892) {
+/* enable multistream for front panel hp */
+       if (spec->multiout.hp_nid && spec->autocfg.line_outs == 4) {
+           spec->alt_dac_nid = spec->multiout.hp_nid;
+           spec->multiout.hp_nid = 0;
+           spec->stream_analog_alt_playback =
+       }
+        if (spec->num_adc_nids>1 && spec->autocfg.num_inputs > 2)
+            spec->stream_analog_alt_capture =
+   }

    if (has_cdefine_beep(codec)) {
