Reversing Audio Jack

Hello dear friends,
I was using Pi for daily development staff to this day. But theese pandemic days I want to dive deep to make a Pi Project.
The question is: I'm using 3b+ and I need to reverse onboard audio jack port. Reverse means, not L swap R, I want to read signal or data from that port. Is it possible?
I don't want to use any hat or gpio solutions, if anyone knows please let us enlightened.
Cheers,
Grim

No. The A/V jack on the Pi is output only. There is no audio input capability.

There is no analogue input capability anywhere on any model of RPi released to date.

You guys are best, thank for your time.
I'll take a new route to make it then.

Apart from the PMIC analogue inputs on a Pi4B (one of two used for checking the pesky USB-C config resistors at the far end of the link -- but maybe not on a v1.2. Or maybe both are used.). The Pi3B+ has the same inputs, unused. Almost certainly of no use whatsoever to "normal" Pi users.

Here's a way to get a 3.5mm input to the Pi without using a hat or gpio - a usb sound card.
That one has a microphone input, and a audio out as well.
