pulseaudio 使瀏覽器中的影片凍結
當我使用啟動（或重新啟動）pulseaudio 服務時，
pulseaudio -k我會播放影片，並且 pulseaudio 服務顯示：➜ systemctl --user status pulseaudio ● pulseaudio.service - Sound Service Loaded: loaded (/usr/lib/systemd/user/pulseaudio.service; disabled; vendor preset: disabled) Drop-In: /usr/lib/systemd/user/pulseaudio.service.d └─00-uresourced.conf Active: active (running) since Fri 2022-03-25 13:42:07 CDT; 539ms ago TriggeredBy: ● pulseaudio.socket Main PID: 92526 (pulseaudio) Tasks: 5 (limit: 308781) Memory: 7.7M CPU: 276ms CGroup: /user.slice/user-1000.slice/user@1000.service/session.slice/pulseaudio.service └─92526 /usr/bin/pulseaudio --daemonize=no --log-target=journal Mar 25 13:42:07 fedora systemd[4316]: Starting Sound Service...
