Ubuntu 18.04 does not see the microphone from the headset, what should I do?

Question

ubuntu

To connect, I use a 3.5mm splitter (because the laptop has only one 3.5mm connector). At the same time, the dispenser and headset are working, I checked it on another device. If you need any explanations or screenshots, write everything off.
