"The internal microphone on this troublesome laptop stopped working
after upgrading from Bionic to Cosmic. There is no signal from the
microphone with kernel 4.18.0-7 or 4.18.0-8.

This DOES work correctly with kernel 4.15.0-34 that is still present on
Cosmic after the upgrade."

I recommend Canonical gets this laptop for testing since a ton of
stuff is troublesome on this Raven Ridge laptop. Would be a good
specimen to get support for this platform improved.
