Quick question, the headphone volume is fine would it just be the resisters on the left I need to replace for the speaker only?

Is it possible to change what the actual button presses correlate to on a keyboard. For example: The start button is the same as the enter key on a keyboard. Because as it is now, the AIO doesn't let you control the linux menus for wifi and such.

One set of resistors is for the Positive rail and the other for the Negative of the audio so both need to be done although if you want to try just one set then you can as I don't know the audio difference it will have.

Of course you can you just need to hook up the board to a PCB with USB connection and use Arduino IDE to program it, I have a guide on it in the Other Hardware subforum. Be sure to skip the Sparkfun part and just choose Leonardo as the board type, I stopped using the Sparkfun bootloader and used the standard Arduino bootloader.

Noob here wiring up the V2.2 AIO. I've been looking for how to wire up the volume wheel but can't find it. In the video guide wermy mentions pins 1-4 and a ground.

It's exactly the same as wermy did in his video the pins are numbered 1 to 4 from top to bottom on the old board and the new one is treated the same. Top pad is considered 1 and 2nd is 2 and so on.

Solved the volume on the speaker, I turned alsamixer volume up to 75 then went into retroarch and turned the volume up to 12db and now the sound is a good level out of the speaker I do however have to turn the volume down when using the headphone socket but that will very rarely get used so not bothered by that at all.

Would these be on the left side labeled RIN, LIN, LOUT, ROUT, GND?

First off, Helder - amazing work with this board. This isn't my first electronics/Raspberry Pi project but this has been the easiest thanks to this AIO. Unfortunately, I'm having a dreaded WiFi adapter problem that seems outside the norm and I'm hoping you guys can point me in the right direction.

Problem:
When my WiFi adapter is connected, it's causing a constant underrun in the alsa lib. On boot, a start job has issues raising the network, eventually fails, and boots into Emu Station. In the RetroPie WiFi setup, no Access Point is listed (obviously since the network couldn't be raise on boot) and the adapter isn't connected to the previously setup Access Point.

Here's the terminal error that constantly runs:
alsa lib pcm.c:7843:(snd_pcm_recover) underrun occurred

Things I've tried:

• I've moved the WiFi adapter to each USB port (1-3) - no change.
• Tested each USB port with my Logitech Keyboard - they all work with my keyboard.
• Tested the WiFi adapter in another Pi (Pi3 in my PiStation project) - works.
• Searched this thread and forum for similar issues - surprisingly none.
• Searched google for known issues with Ralink RT5370 interfering with alsa lib - nada

Important info:
I'm using a Canakit USB dongle that's really a Ralink RT5370. This adapter was purposely setup before I started the project and was working before I even got the AIO. I've also made sure to set USB to 1.1 in the cmdline.txt file and max USB in the config.txt file. All soldering points are correct, all soldering points are solid (no breaks or shite solder points), and Data wires are twisted and shielded. The AIO Hub is confirmed to work with my USB Logitech Keyboard without issue.

Any help is appreciated.

I got this working with a pi3 inside a gameboy woohoo. Thanks
