Help me salvage this

Post by Robochris » Mon Dec 09, 2019 2:17 pm

long story short, (chronicled here - https://www.sudomod.com/forum/viewtopic ... 776#p77842)

My audio doesnt work. I removed and tried to reinstall the audio chips few time and think I ended up lifting pads to the chip.
so my brain thinks I can wire an i2s board to the pi, volume wheel, and (probably skip the head phone jack. I dont use it) then speaker.

am I right? how do I know which gpio pins to use?

I really enjoyed this thing when it worked and I dont know exactly what went wrong to begin with. Help me game again.

Hey, before doing anything else I would rule out the volume wheel being the issue using the pin out below by bridging the 2nd and 5th pins and 3rd and 4th pins and then turning it back on and seeing you have audio through the speaker/headphones or both
