Thank you so much!
Will this work for all G751 models, and will this be in the 4.19 kernel?
I am very thankful for all your hard work!!

Everything seems identical to how it was in the 4.18-gentoo kernel when

And using the trick we found:

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

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.
