我正在尝试激活回声消除模块。我添加了行load-module module-echo-cancel，但当我尝试重新启动时，pulseaudio出现此错误：
E: [pulseaudio] module-echo-cancel.c: Master source not found
E: [pulseaudio] module.c: Failed to load module "module-echo-cancel" (argument: ""): initialization failed.
E: [pulseaudio] main.c: Module load failed.
E: [pulseaudio] main.c: Failed to initialize daemon.
以前我使用过 antergos 并且没有遇到任何问题pulseaudio。
重新安装后pulseaudio，我开始收到此错误：
cannot cancel echo between a sink and its monitor
