** 无声音问题：搭载 Intel Sunrise Point-LP HD Audio 的 Ubuntu 22.04 出现“虚拟输出” **
描述： 我在 Ubuntu 22.04 系统上遇到了声音问题，希望有人能帮我解决问题。目前，我只有“虚拟输出”作为唯一可用的声音输出设备。
系统信息：
- 操作系统：Ubuntu 22.04
- 核心：Linux Swift 6.2.0-33-通用#33~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC
- 音频控制器：英特尔公司 Sunrise Point-LP HD 音频 [8086:9d71] (rev 21)
采取的故障排除步骤：

尝试重新启动、重新安装 pulseaudio 和 alsa，但没有任何效果。
答案1
我不确定，但也许你可以用以下方法解决：
sudo touch /usr/share/pipewire/media-session.d/with-pulseaudio进而
systemctl --user restart pipewire-session-manager
答案2
请尝试此处列出的步骤：
没有声音：main.c: pa_pid_file_create() 失败
内容是：（rm ~/.config/pulse/*或者如果自 2019 年以来发生了变化，则使用类似的说法）然后重新启动。祝你好运。
PS 我通过搜索 AskUbuntu 找到了这个线程，[pulseaudio] main.c: pa_pid_file_create() failed.这样做通常会找到有同样问题的人创建线程。
