I am using Rpi-Webrtc-streamer for webrtc on raspberry pi with usb sound card connected to audio amplifier for speakers and electret microphone. I am able to run webrtc correctly but with issue of mic catching echo from speaker. I have tried to enable echo processing as provided by library but didn't work. Echo is not at all removed. In fact there are no change invoice quality by any of audio processing.
I have also tried using this library for software echo cancellation but it is not working with webrtc streamer. Is there any way to work around the issue of echo as it is very important for us to remove it.
