Hello I finished my build but I have this big issue the left audio channel works just fine but whenever i check the right audio and get static feedback mixed with the left audio as well and when I try to connect both left and right channels into the speaker i get no audio and just poping and crackling noises. I been trying to see if there's a tread online but so far no one has experienced this problem


Is there a way that I can connect the right audio to another pin to see if that works or is there a way to make the PWN output mono from the pizero.

You might take a look at Helder's Support-Thread: http://www.sudomod.com/forum/viewtopic.php?f=5&t=1185

Show us the wiring of the pi and headphone socket. Also is your pwm config.txt entry correct? You can set the pwm as mono and if you did without realizing it then the right channel would be giving you the issues you're having now.

Pictures help determine the issue so post some photos.

I'll be uploading pictures and heres the config.txt

Now I have this bigger issue the controller is not being recognized at all I have to plug in a usb keyboard to navigate is there a fix for that?
Also everything else in the all in one board is working it's just the controllers are not being recognized.

Support thread has the answer for controller not working and my working config.txt and cmdline.txt which you can add to your SD card.

When the controller stops responding or isn't detected it usually is some corruption in the SD card and a fresh Retropie install fixes the problem.

EDIT: I have tried a fresh install of retropie and used the config.txt that the forums provided and the audio doesn't work all i hear is a very faint music and static,

ALSO: using the fresh install of retropie and reformat the sd card did not fix that gamepad problem it is still not being recognized even in the fresh build

Increase the volume in the retropie settings. If you connect the controller to a PC does it recognize the Arduino as a Gamepad? Almost everyone who had the same issue as you reinstalled a stock image of Retropie and it fixed the problem with controls, maybe try Retropie 4.0.

Hello Helder I have connected the All-in-one board via USB to my computer and the arduino gamepad is not being recognized the only thing thats being recognized it's the usb hubs but thats it. Could it be that the arduino is dead?

ALSO: I've tried retropie 4.0 fresh install

Did it work before when you had audio issues? Try reprogramming the arduino again, if not then it likely needs a reflow or has a bad trace on the board. I have one here that programs fine and reads the usb hub but the arduino isn't being detected and I assume it's a possible bad trace on the board.

Try reprogramming it first then if that doesn't work PM me and we can do something to replace that board.

I tried reprogramming the arduino but no luck it's not being detected I've send you a message to see if we can work something out. thanks!
