I'll try to answer your previous email first.
Everything seems identical to how it was in the 4.18-gentoo kernel when not setting the model=alc668-headset option
And using the trick we found:
./hda-verb /dev/snd/hwC0D0 0x20 0x500 0xc3 ./hda-verb /dev/snd/hwC0D0 0x20 0x440 0x00
OK, then the following patch may work. Give it a try.
Made it so loopback worked perfectly fine for both earpieces.
One curiosity however (this is just a small thing) is that the "base" mic level is far lower than when the "Mic" option in alsamixer is set to 100. I don't know if it was this way in 4.18-gentoo, but that's the only thing that doesnt seem correct. Here is a screenshot explaining it: http://i.imgur.com/dKPELX6.png
The Mic volume is only for analog loopback, so it can be normal.
