无法启动 jack 服务器？服务可用（org.jackaudio.service 又名 jackdbus）。

我尝试使用 QJackCtl 启动 jackd，但失败并显示错误消息，以下是我所看到的 -

注意：如果我重新启动机器，“Jack”就会重新开始工作，直到我使用 vlc 或任何其他媒体播放器播放某些内容，例如电影或歌曲等。

我是新手，但我会尽力回答你的问题。听起来你可能正在经历与我类似的经历。在终端中尝试一下。这是代码。

pulseaudio --kill
jack_control  start.

然后，当你完成 jack 后，请执行以下操作。这是代码。

jack_control exit
pulseaudio --start.

我希望这有帮助。
