在关闭和启动我的桌面时,我有时会在系统日志中收到此错误:
pulseaudio[1710]: Can't cancel echo between a sink and its monitor
pulseaudio[1710]: Failed to load module "module-echo-cancel" (argument: "use_master_format=1 aec_method=webrtc aec_args="analog_gain_control=0 digital_gain_control=0" source_name=echocancel"): initialization failed.
pulseaudio[1710]: Source echocancel does not exist.
这阻止了模块回声取消在 xubuntu 20.04 中加载。
我/etc/pulse/default.pa
看起来像这样,似乎在 18.04 中起作用:
load-module module-echo-cancel use_master_format=1 aec_method=webrtc aec_args="analog_gain_control=0 digital_gain_control=0" source_name=echocancel
set-default-source echocancel
当我重新启动后重新启动 pulseaudio 时,pulseaudio -k
module-echo-cancel 可以正确加载。
知道为什么这个模块在启动时不能正确加载吗?
