Ok so you have just put 2 resistors in parrallel of the speaker (the end of R15 &R16 are directly connected to speaker+)

So in theory we just need 1 resistor (150o) between speaker+ and-... This is weird but I will try this hack tonight.

Ok so if the headphone is working there are 2 possibilities that could be the issue: 1. Bad Headphone socket or soldered on badly 2. The mixing Resistors R15 and R16 are bad and not combining and letting the audio pass to speaker. You can also test it out of the Left or Right Headphone In pads too ...

Hi helder

My headphone socket have 5 pin, and I've checked continuity ... everything is ok.

I would like to understand why the PAM work only when the headphone is plugged.
Could you please send us the schematics ?

Thanks

Hi helder, First of all, thank you for this board. Everything works except the sound. I've got exactly the same issue as Tomatoflames and xfcrowman. When I plug an headphone I've got a clear sound, but when this is unplugged I've got no sound on my speaker. I've tried 3 different speaker from adafru...
