Audio Difficulty with Pi 2x Board

[Aaron, N3MBH]

I think I’d let Dan comment first to see what thoughts are since you seem to indicate it is not an issue on different hardware.

Can you explain the setup in enough detail to where we can try to reproduce the echo? what port are you using, where are you hearing the echo, how loud is the echo, etc. the more details the better.

We have only ever heard about this one other time and were never able to reproduce the symptom. It is certainly possible there is a corner case, although the audio paths are completely separated except inside the audio codec chip.

I managed to sort the echo problem. I had to turn down the audio input level and adjust the gain and output level of the ICS pi 2x controller board

Great, glad you were able to find a solution
