I have the exact same symptoms using Debian Sid. And I -have- read through all 38 pages of this topic, as well as all the other info I could find.
When I boot from an SD card with Mr Fixit's version of Debian, speakers and headphones work as expected but still do not show any additional controls in alsamixer or pavucontrol-qt. That kernel is ancient 4.6, I think.
i.e. When I plug in the headphones the speakers stop making sound, headphones work and actually sound pretty good (Grado wireless but with the wire plugged in). When I unplug the headphones the speakers emit sound again and the headphones stop : )
I looked through all of the alsa related files on Mr Fixit's Debian but did not find any real difference. There was an asound.rc file in /etc but it was very simple and had no effect on the problem we are having.
My guess is that this is a kernel issue but I am not quite ready to start swapping around kernels.
Sorry, I don't have a solution but hopeing the slight additional information might help someone smarter than me figure it out.
