pulseaudio 10.0 pactl load-module module-echo-cancel aec_method=webrtc pactl load-module module-echo-cancel aec_method=webrtc aec_args=agc_start_volume=200 or without aec_method or other arguments. So far I could see the microphone slider move left only when the gain is 100% and I yell. When I set the gain to low the slider does not move at all to pick my voice. On fedora 24 automatic gain control for microphone with module-echo-cancel works fine. On fedora 24 at the time of writing there is pulseaudio-8.0-6.fc24. From PulseAudio 9.0 release notes [1] > It's now possible to configure the initial volume when using AGC (automatic > gain control). To do that, pass "agc_start_volume=VOL" in aec_args when > loading module-echo-cancel (replace VOL with a number between 0 and 255). > Note that too low initial volume may prevent the AGC algorithm from ever > raising the volume high enough (there seems to be some regression in the > WebRTC code in this regard). Would the above change affect the automatic gain control that it does not work for me anymore?
