为什么脉冲音频被报道为没有运行？

Question

我有Ubuntu 21.10，我得到了与pulseaudio相关的以下结果。我应该做什么来“连接”到pulseaudio，这样pacmd list-sinks才能正确地报告某件事情？

$sudo netstat -tlupn | egrep -i "mopidy|pulse"
tcp        0      0 0.0.0.0:4713            0.0.0.0:*               LISTEN      1730/pulseaudio
tcp6       0      0 :::4713                 :::*                    LISTEN      1730/pulseaudio

$pacmd list-sinks
No PulseAudio daemon running, or not running as session daemon.

$ps -ef | egrep "/[p]ulseaudio"
lightdm     1730    1668  0 Oct30 ?        00:04:35 /usr/bin/pulseaudio --daemonize=no --log-target=journal

为什么脉冲音频被报道为没有运行？

因为脉搏不快！

据我所知，Ubuntu用21.10把电源线转换成管道
