没有声音：main.c: pa_pid_file_create() 失败

我无法使用，pulseaudio所以在 Ubuntu 19.04 中根本没有声音，我的笔记本电脑是 Lambda Tensorbook。有人能帮我解决这个“头痛”吗？提前谢谢。

答案1

如果您最近更新了 pulseaudio 或恢复了旧的主目录或配置文件，您可以尝试：

rm  ~/.config/pulse/*

这应该会删除当前显然不起作用的 pulseaudio 默认设置。

此后，请重新启动系统以构建新的 pulseaudio 配置文件。

答案2

我：[pulseaudio] main.c：使用模块目录 /usr/local/lib/pulse-12.0/modules。

看来您自己编译了一些与 pulseaudio 相关的内容。在/etc/ld.so.conf.d/指向的条目下的文件中添加注释/usr/local/lib/。使用sudo ldconfig -v更新/创建链接和缓存来获取新的库。
