The important part is not to use the ampifier for the headphones, and you dont need that, because the display can drive headphones.
The amplifier is only needed for the loudspeaker. And because the loudspeaker needs mono, i mixed the stereo signal with the 10k resistors.
if you read post you will see this is how is in the project already
Do you have a problem with me ? The first post talked about connecting L+R together and that it was generating noise.Codemaster123 wrote: ↑Thu Nov 16, 2017 12:29 pmthank you i really appricate itsalami738 wrote: ↑Thu Nov 16, 2017 12:21 pmI uploaded an image for you

the screen you connect or still need to connect

The last post is talking about mixing L+R with resistors, where do you read that it's actually what he has done ?
The solution of VeteranGamer can be of use, if you only want mono sound.you are only using the left channel (L+ / L-) on the output side.
So if you are emulating games with stereo sound, you will only get the sound of the LEFT stereo side of both sides of your headphone (your signal path is: stereo -> only left side -> dual mono left side).
You have no static on your build, because you dont have the outputs of the PAM8403 connected.
In reality you don't get stereo sound but a mixed L + R channel over monaural output. But i agree that, in that way, you are not loosing half way one channel.salami738 wrote: ↑Thu Nov 16, 2017 12:47 pm@YaYa and @Codemaster123: I thought about using the schematic from VeteranGamer, but as i mentioned earlier:

If you want stereo sound (e.g. SNES), you should think about an other solution (i use the schematic i posted).
