The integrated microphone as well as the 3.5mm generally do not work, but there seems to be activity in pavucontrol (I think this is white noise). I tried anything - building kernel 5.5.6 and updating alsa to 1.2.1, but it does not seem to help. The microphone does not work, but speakers do. I am using Ubuntu 19.10 with the new Inspiron from Dell - 7590 ( model info from Arch Linux)
