My Raspberry Pi 3B has many issues.

Hello, I just built a raspberry pie bar top arcade machine with a raspberry pi B+ then upgraded to raspberry pi 3B.

I have many problems with the raspberry pi 3B after upgrading it. I did not have these problems with the raspberry pie B+

First, I cannot get it to detect the GPIO pins of my joystick and buttons, but I can get my USB gamepad and keyboard to work. All I’m trying to do is to get the control panel to work. I think I connected them correctly.

Second, I’m seeing the lightning bolt constantly, so I have a low voltage warning. I am using a 5 volt 3 amp power supply which I believe is the correct unit. I did overclock it though with the heat sinks. I am using a DC power supply connected to a DC Jack which is connected to the pi.

Should I switch to the official power supply? The no voltage warning also showed up a little bit with the Raspberry Pi B+

Lastly, I’m getting no audio whatsoever. I made sure that the audio was plugged in, I tried to fix it in the settings of retro pie and tried editing the command prompt. Still, no audio. I even tested the speakers with my iPhone and it works fine. I’m totally A beginner when it comes to programming so I really need help here.

Should I get an updated Raspberry Pi 3B+ because I read they have less issues, or should I update the software since it’s been sitting there for a while.

I built the raspberry pie from this website:

I would appreciate any advice.

@trip238 Did you start with a fresh install? You seem to imply that you just pulled out the old pi and put in the new. In any case you should back up your roms, configs and saves then start with a fresh install of retropie.

Pi 3s are more demanding power-wise than the older models, though 5v 3amp should be plenty. I can't be sure about issues with DC power, is that coming from a DC converter or through a native DC power outlet? Sometimes voltage issues occur with shorts or other problems with cases. Overclocking the pi in certain cases will cause it to draw too much power as well.

Looking at the pin-outs for pi b+ vs 3b, they look similar but there is no telling. Looking at the website you linked I would imagine that information is somewhere in his documentation.

I would start be taking your pi, put a fresh retropie install on the sd card, plug it into a 120v outlet, connect it to a tv with hdmi, and connect a game pad. The point is to have nothing else connected. If you are still having voltage issues then you should look for a new power supply. I would be willing to bet your audio issues will be resolved with a software update.

The Pi 3 and 3 B+ need a good quality supply, with good connection to the board and a thick wire. Your setup fails on at least one of those requirements. I would recommend getting the official power supply. It simply works. Even with my 3 B+ heavily overclocked, I have never seen the lightning bolt.

It doesn't hurt to run through the all the audio settings again

#/boot/config.txt
dtparam=audio=on

raspi-config
Advanced Options >> Audio >> Auto|Force

Emulationstation
"Start" >> Sound Settings >> Audio Card=Default/HW?, Audio Device=?
