I assembled a PT8211 and connected to a 3.2 board. I did not install the headphone jack, instead I hookup some some wires to see if I can figure out how to reroute it to a panel-mount 1/4 jack.
Based on a little time with the jack and a 2.5mm TRS male to male cord I deduced that I would get audio signal for the left channel between the GND and outside LEFT pin (green and yellow in my picture) and I would get signal for the right channel between GND and the outside RIGHT pin (Green and blue in my picture). Yet no luck running the PT811Sine example. I have tried several other combinations including the two pins on each side and ground to the inside pins and still nothing.
I did modify the code to output to the 3.2 onboard DAC and did have success so I know that my cord / amp / jack setup is legit.
Note in the wire (yellow / blue) on the outside pins are soldered from the other side of the board
Any suggestions?
