PMW audio help

I am almost finished with my first build but I am unable to get the audio to come out. I edited my config.txt file by adding,
"dtoverlay=pwm,pin=18,func=2"
and I tried my best to follow this diagram

But when I power it all up I hear that the speaker is on and making some sort of sound but no audio from the game. When I turn the volume wheel the white noise sound gets louder so it seems like its wired correctly. Im not sure where to turn. Anyone have a good video or tutorial?

Try turning back and forth the pot on the audio amp. Try just the speaker for now without the headphone jack.

If you're using an older zero - have you tried the newer audio driver?

Or, If you can ssh in - or you have tiny terminal on the pi, try playing an mp3 direct to confirm it's not your es settings
