okay. so i just hooked everything back up how it should be and I have sound. when i bridge the channels, I lose sound again.
Thoughts why?
You need resistors for each If you want to combine the two output channels. 10ohm-15ohm resistor should be fine. Or you can combine both the left and right audio from the Pi into a single audio output.
