load-module module-echo-cancel aec_args="analog_gain_control=0 digital_gain_control=0"
+
in the file:
/etc/pulse/daemon.conf
or
~/.config/pulse/daemon.conf
Uncomment the line, and set to no:
flat-volumes = no
load-module module-echo-cancel source_name=logitechsource
and then at the bottom of the file add
set-default-source logitechsource
In this case I named the source logitechsource, but you can name it whatever you want and simply either restart pulseaudio.
