Yep a 330ohm as a load fixed the audio too.

As a matter of fact, just by touching the 3.5mm tips with my finger (me as a load) makes things much better.
I would have to assume that any resistance creates a reference voltage from a current source for the OSSC ADC, I would also have to assume that the OSSC has no analog circuitry before its ADC..?

As you can see in the schematic, the headphone output of the MD1 expects a speaker load.
Any ADC expects a Voltage on a Load.
