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 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.
