在终端中使用后重新启动 pulseaudiopulseaudio -k然后pulseaudio --start我收到以下输出。
E: [pulseaudio] main.c: Daemon startup failed.
当输入时pulseaudio -vvv我收到以下输出。

有没有什么办法可以让我重新启动 pulseaudio？
答案1
我也遇到了同样的问题。太烦人了。
在我的计算机上，这似乎是由于 pulseaudio 已在运行，但可能仅响应systemctl命令。我暂时采取的方法是让声音响起：
$ ps aux | grep pulseaudio- 终止所有 pulseaudio 进程
$ rm -rf /.config/pulse/（强制 pulseaudio 重新生成配置文件）$ pulseaudio --start
一切如预期。
如前所述，这不是真正的解决方案，但在进一步排除故障之前它应该能发出声音。
答案2
我在 22.04 中遇到了音频问题，错误
[pulseaudio] main.c: Daemon startup failed.
在阅读了很多毫无帮助的建议后，我按照以下步骤操作。
- 我将其重命名
~/.config/pulse为/.config/pulse.old
然后重新启动 Pulseaudio
pulseaudio -v -D。
最后，我的音频通过笔记本电脑内置扬声器播放出来。还需要在 HDMI 端口上解决这个问题。
