Microphone feedback sound too loud on some device.

[affifymirza]

Has anyone experienced receiver feedback noise? Is this problem fixable? Some of my testing devices function perfectly, while others make too much noise even with same model and build.

AudioParam audioParam = new AudioParam.Builder()
                    .setUsingOpusCodec(true).setSampleRate(16000).setFrameSize(960).setChannelSize(1)
                    .setAudioSource(MediaRecorder.AudioSource.MIC)
                    .build();

        VoicePing.INSTANCE.init(VoicePingService.this, "wss://router-lite.voiceping.info", audioParam);
