PWM Audio Filter + Amp Stereo

[VitaliBR]

I'm creating an AIO-style PCB (I want to learn, so I'm creating my board). I'm using a raspberry PI zero.

To create the audio, I chose the PAM8403 IC because it is a stereo. First I made the pwm filter for raspberry using pins 0 and 1. Soon after the signal was sent to PAM8403. Is the schematic correct?

Another question is about the headphone, I have read a lot about it, but I did not understand and I could not find a solution to put a p2 jack for headphone because the ground is not common for L and R.

Sorry, I'm graduated in software development, I'm self-dictated in electronics.

My schematic:

Hi I am still learning myself but from what I have learned the headphone jack will go before the amp

Thanks for the reply, but in that case it is using USB audio. Is different from my project.

The question is how to use the PAM8403 which is class D with headphone:

Note: The left and right channel output of the "negative" can not be connected together, otherwise it will burn IC, and should be preceded powered speakers connected (load).
