First post explained how to get wifi working but just solder a wire to each of the 22 ohm resistors. They are the located right above the atmega32U4 chip on the far right of the components there.

I'll post a picture soon.

Hey Helder !
Sorry, was this for jsawhite or for me ?
Also, on the picture you posted, basically you mean two wires, one from the D+ and one from the D- (that are on the far right usb) ?
Why is the 5v in read ? And this will fix wifi for everyone you mean ?

Thanks !

The diagram wasn't for you but the USB fix was as well, have socket on the board or use wires to a socket then plug in a keyboard. If you did the usb fix not all keyboard will work for you in this mode unfortunately and check that you don't have a short of some kind and that the power supply might not be outputting enough power for all of this.

Hi Helder!

I have a short question. I'm using a Raspberry Pi3 and I have the audio out of course. Can you tell me where can I solder it directly to the AiO board so that I skip the PWM but still use the amplifier and, pots for volume controls etc. It's your 1.4version.

I've put everything inside. Now just need to solder the things and that's it. Can't wait (finally...

Wire the Right output to the Volume Wheel pin 1 and Left output to Volume Wheel pin 2. You can wire everything else as in the wiring diagrams on first post links.

So Pot 1 and Pot 2 it is. Thanks a lot

Tried all the fixes, nothing works. Kinda sucks not being able to use my AIO because of the USB issues, wouldnt have ordered if i had known that there was this much trouble just getting some devices to work at all, much less 1.1 speeds.

I feel your pain, and the new board has the same issues, saw a post were Helder said the chip he used does not play nice with the pi, asked what people wanted to do, wait for a new chip or put up with a product that does not work as it was intended. Nobody really complained so he used the same chip.
I added a switch( located in the upper left part of the battery compartment) to the usb wiring from the pi, so I could send the signal were it needs to go: either the aio or the upper usb hub. For me my usb key board did still work with the usb from the aio so I added a second usb hub to the battery compartment.
With the switch up I only get usb to the usb hub(aio not connected) this way all my usb devises work, keyboard, Wi-Fi and memory stick.
Down position I get usb to the aio and the hub in the battery compartment, that way I can use the keyboard to map the aio keys in the mame games.

Everyone who complained about the fixes not working often didn't follow the directions or used in compatible wifi cards and keyboards but once they did follow directions it often worked.

It's true not all keyboards work and not all wifi cards work then again not all usb hubs work 100% either (blame it on the Pi) but I've had success along with many others with the 1.1 speed fix.

Hello, I'm struggling with audio: I cant't get any sound.
I edit my config.txt and add : dtoverlay=pwm-2chan,pin=18,func=2,pin2=13,func2=4
My wiring seems good:


Do you have any ideas how to get audio?

[msykos]

I had to make that line of text its own line, not add it to the end. Then my audio worked fine. Hopefully that helps. You can also try just wiring up the speaker to make sure the issue is not in the jack.

[jeff_lequeux]

the dtoverlay line is already on it's own line....
I also try to change the jack for the original GB GMG one, with no luck
I also try to change the volume wheel for the original GB GMG one, with still no luck
