How to broadcast the sound of a microphone (voice meter) to another PC?

Question

Audio

There are two PCs and jack-jack.
1 takes the sound of the microphone, processes it, and forms a virtual recording device through Voicemeteer Banana, which is already used by applications. This PC will continue to use the microphone, but it needs to be duplicated on a jack-to-jack wire.
2nd pc. I want to achieve that this PC would receive a "microphone" via the jack-jack wire and use it as a recording device.
I've tried fiddling around with device settings but to no avail.
Actually, I'm not sure that I can do it without a sound card, so if it is 100% necessary, then write what minimum capabilities it should have. I heard something about loop-back, but have not had time to figure it out yet.
Thanks in advance.
