I bought the circuit playground express because of the DAC on pin A0. Currently I am trying to send an analog signal from my SEN-12642 sound sensor from analog pin A3 to the DAC analog output A0. Examples I have found use PWM but I don't think that will work for my situation because of the true analog output.
Thanks,
Ben

Please post a link to whatever that is.

An analog input pin returns a digital value corresponding to the voltage sampled, not an "analog signal". If your gadget has a genuine DAC, then it is entirely appropriate to send the DAC a digital value.
Here is the board I am using: Pinouts | Adafruit Circuit Playground Express | Adafruit Learning System
I am just trying to get my information from A3 so it can go through the digital analog converter on pin A0.
So, what is the problem? Assuming Arduino instead of the two other programming interfaces, have you considered using analogWrite(A0, value) to output a voltage?
