@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.
