kernel 4.15.0-99-generic: no internal sound / no sound through earphones audio jack

kernel 4.15.0-99-generic-revert225, kernel 4.15.0-96-generic, kernel 4.15.0-91-generic : sound works as expected (both internal and through audio jack)
[However, if my earphones are plugged in prior to booting, then no sound will come out. I must unplug them (sound will come out through internal speakers), and then plug them back in. Probably a different issue though, as it isn't new.]

For all kernels, I hear a brief clicking sound through my earphones when booting and rebooting.

I attach alsa-info.txt for kernels 4.15.0-99-generic-revert225, 4.15.0-99-generic and 4.15.0-91-generic
