I believe I'm having the same issue on a Dell 7591 15" 2-in-1 running Ubuntu 19.10. With no headset plugged in nothing shows up under Sound->Input. If I 1) plug in headset (select Headset in the pop-up) 2) Open Sound 3) Select Microphone Built-in Audio under Input 4) Select Headset Microphone under Built-in Audio...then input audio is picked up but is scratchy as OP mentioned.
