We are designing for an audio applicaiton which requires headphone output and mono microphone input. I have been using the GUI to configure a development board (170-04-A and 169-02-A) and have got the headphone output to work well, but the microphone input has a lot of noise on it and i cannot seem to get rid of it. We require a single ended microphone input on MIC1_N which I think i have configured correctly. I have attached a dump of the registers from the GUI to this post. Do you have any advice on whether our setup is correct or what settings we can change to try and remove the noise?
