I am using Ubuntu 19.10 with the new Inspiron from Dell - 7590 (model info from Arch Linux)
The microphone does not work, but speakers do. I tried anything - building kernel 5.5.6 and updating alsa to 1.2.1, but it does not seem to help. 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). Also there is nothing shown as input (when I go to settings -> sound), but I can see something in pavucontrol
My multimedia controller is:
00:1f.3 Multimedia audio controller: Intel Corporation Cannon Lake PCH cAVS (rev 10)
DeviceName: Onboard - Sound
Subsystem: Dell Cannon Lake PCH cAVS
Flags: bus master, fast devsel, latency 32, IRQ 177
Memory at ed318000 (64-bit, non-prefetchable) [size=16K]
Memory at ed100000 (64-bit, non-prefetchable) [size=1M]
Capabilities: [50] Power Management version 3
Capabilities: [80] Vendor Specific Information: Len=14 <?>
Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+
Kernel driver in use: snd_hda_intel
Kernel modules: snd_hda_intel, snd_soc_skl, sof_pci_dev
No input devices show by default on clean install of Ubuntu. I tried 18.04 (LTS) but the result is the same, so I switched back to 19.10. When I run pavucontrol
it shows this:
I can see noise and that the mic is recording something (but I cannot control it from the sound settings) but it does no react to my voice.

I hope someone can help me out here, I would be really grateful. Thanks in advance!

Update: seems the mic now works under Archlinux: https://wiki.archlinux.org/index.php/Dell_Inspiron_15_(7590)
Update #2: With a little help from sof developers, I think I can get my mic (as well the one from many other dell laptops) working - https://github.com/thesofproject/sof/issues/2502
