Nano-pi neo air analog audio output

I am new to nano-pi air neo. I am trying to get analog audio from the
device. I tried with the four connectors near to the camera connector in
the device, but it was not a success. But when I connect the speaker to the
DOUT of the audio (which in I2S port), I get the sound but with lots of
noises. How can I get clear audio out in this device ? Am I missing
something here ?

Thank You

I suspect that I2S is totally digital and some bit of hardware would be
needed to do the translation to analog audio.

Try a Google search <I2S to analog audio>


Also I suggest the new forum for questions on their new devices.

Good luck!
