Unfortunately that's the only oscilloscope I have right now. I checked the GPIO schematics and I am getting the signals and grounds properly connected. The only thing I noticed is that it says VCC instead VDD which according FvM comment, not sure if they made a label mistake or definitively the GPIOs are not LVCMOS. Anyways, I went ahead and decided to send that signal to the codec and am getting the analog audio to the digital stream as it should so the codec understands the that wave form, whatever it is.
