How can I check if I2S is active? Im not sure really. I just kept reflowing the solder points with the tip of my iron. I did have my system on and a game running with the sound at high volume so you know when you find your weak spot lol. Edit: I would also double check all your soldering on the sur...

Yes actually, late last night. Not sure which pin but I reflowed solder on the audio chip and surrounding components several times. Everything seems good to go now.

It was the OUTP connection on the AMP chip. I had pulled the pad accidentally. Made a new one with a single fiber of copper. Working perfectly now.

Good to know! I hope mine can be an easy fix too.

I’m in the same boat. No sound. But I think I have everything soldered correctly because I have a lot white noise and game music is extremely faint, even at full volume. I’ve messed with a few settings but no results yet.

Reflowed solder for the third time and that seemed to work. Odd because I had continuity on all points. But oh well, it works. Now for my audio problem.

Check your pololuand tp4056 are installed correctly

I’ll check again but I have reflowed and checked continuity. I’ve tried following the traces from the power pins on the Pi but but end up at the screen or audio circuit.

Ok. I am able to boot into emulation station without any issue. However, I was only able get my board to boot by bridging two of the side contacts on the S2 spot. I originally had a momentary switch on here, but later determined that I could only get power if I was holding the switch down. Not sure...

So I got all the components soldered on. I’ve followed every trace I could find. It seems like the Pi isn’t getting power. I have lights on the charger and on the small board with the switch that come on. I don’t know what to check from here. Also should I be able to detect continuity on both sides ...

How are you transferring roms without samba then?

I’m here for the same reason. Looking for pinouts and smd component layout. Just follow the traces, it's a completely optional step. What do you mean by and component layout? There’s a few on the ads1015 that I can’t seem to trace. Are not all of them used? I think I figured out the resistors and c...
