@Jeremy,

Many machines have their internal mic connected to the PCH, to make the
internal mic work, the kernel needs those changes. And if you want the
sound to work as before with -43 kernel, you could add "snd-hda-intel
dmic_detect=0" in the /etc/modprobe.d/alsa-base.conf, then the audio
will work as -40 or before.

thx.
