从 20.04 LTS 升级后，Ubuntu 22.04.1 LTS 没有声音

Question

我的运行 Ubuntu 22.04.1 的 ThinkBook 14S-IWL 笔记本电脑不再有声音。

\n

我已经尝试了一切：重新启动、定期关机、apt-update、更新 GRUB、尝试安装 pipeline/wireplumber/pipewire-session-media 并查看是否有效，但没有成功。

$ systemctl --user daemon-reload

看似什么也没做。终端没有抱怨，但我仍然没有音频。

\n

$ pactl info | grep \'^Server Name\'

\n

Server Name: PulseAudio (on PipeWire 0.3.48)\n

\n

$ aplay -l | grep HDMI

\n

什么也不返回。

编辑：将 3.5 毫米耳机插入耳机插孔并重新启动后，我可以通过耳机听到声音。但如果我拔掉耳机，就听不到声音。

编辑2：现在我不再有声音了。我一直在更新和升级 Ubuntu，但仍然没有解决。

Answer 1

我遇到了完全相同的问题，为此我在从 21.10 升级到 22.04 后没有列出声音输出设备中找到了解决方案：

sudo touch /usr/share/pipewire/media-session.d/with-pulseaudio
systemctl --user restart pipewire-session-manager

Answer 2

升级后我也遇到同样的错误。对我来说，临时解决方案是运行

$ systemctl --user restart pipewire pipewire-pulse

每次启动后。最后我发现/usr/share/pipewire/media-session.d缺少了

$ ls -ld /usr/share/pipewire/media-session.d
ls: cannot access '/usr/share/pipewire/media-session.d': No such file or directory

和

$ sudo apt --reinstall install pipewire-media-session

为我解决了这个问题。互联网上的一些报告称您可能希望在运行重新安装之前创建此目录（恕我直言，可能不需要）

编辑： 虽然此后音频对我有用，但错误消息

mod.rt: could not set nice-level to -11: Permission denied

留下来，最后我还必须附加

@audio   -  nice     -20

到/etc/security/limits.conf（如此处所示）从日志中删除任何错误消息。（重新安装rtkit对我来说也不起作用）

我检查了日志是否干净：

journalctl -b 0 --user-unit=pipewire --user-unit=pipewire-pulse --user-unit=pipewire-media-session --user-unit=init.scope
