I have this duo that was worked on before and they seemed to have lifted the right pad to cap C323
and took the surrounding traces. This gives it zero sound. like a switch was pressed. never encountered this before.
I have wires soldered on the spots with nowhere to go:

the best picture i could take.
using duor's picture:

i need to know where pin 3 goes to what resistor or point.
any help would be most appreciated and will result in a prize :wink:
if i had a due board id tell u directly.
pins 2 and 3 are differential inputs.
generally pin 3 will have a capacitor connecting it to the sound source
pin 2 should have a cap to ground and a resistor to 1.
alternately the cap on 2 can be connected to source and 3 to ground without much change in function.
i just saved and brightened that pic.
is that the duo in question.
is pin 2 and 3 jumpered together
look at the blue line
thanks for the input steve. i checked all my other duo boards and it looks like that cap forks in 2 directions so i soldered those 2 wires to the cap. it didnt help my problem of zero sound but the repair looks like its stable and holding. i wont know for sure till i find the main problem. thanks again.
