I would like to know if there is a method with the raspberry pi for reproduce the audio from pin using pwm, or by some other metods.
Thank you in advance.

That's precisely what you get on the analog audio 3.5mm jack. It can even be done on a RPiZero with some simple additional hardware.

Does your Model B not have a 3.5mm audio jack socket?

No. You might be able to get raw audio PWM by remapping pins, but you'll be missing the RC filter circuit to get usable sound.
