我在装有 Ubuntu 22.04.2** 的联想 P15s 笔记本电脑上遇到了声音问题
实际上根本没有声音；声音设置显示单个“DummyOutput”条目：
我讨论了几个主题，其中最相关的是：
没有成功。
以下是更多信息：

** 在固件升级之后，显然出现了问题，因为每次重启时，它都会写入类似
1) "Reading ME Firmware... Please do not power off! 50% Completed"
2) "Recovering ME Firmware...Please do not power off! 10% Completed"
3) "Failed to recover ME Firmware..."
我尝试重新安装从这里下载的可用固件：
- cab文件：https://download.lenovo.com/pccbbs/mobiles/n34rk01w.cab
- 自述：https://download.lenovo.com/pccbbs/mobiles/n34rk01w.txt
但令人惊讶的是（！）联想没有提供适用于 Ubuntu 22.04 的固件：
但它根本不起作用：
$ sudo fwupdmgr --allow-older --allow-reinstall install n34rk01w.cab

我尽量详尽，但可能遗漏了一些关键信息。如果是这种情况，请随时告诉我。
我只是希望我的声卡能够再次正常工作。
答案1
我通过运行建议的命令解决了这个问题这里，由 github 用户 ruimbribeiro 撰写，他在 Lenovo T14 Gen2i 上遇到了同样的问题：
$ sudo fwupdmgr reinstall

2 <-- picking the second entry
# (...)
# reboot
然后，在系统重启期间，我再次遇到同样的错误：
1) "Reading ME Firmware... Please do not power off! 50% Completed"
2) "Recovering ME Firmware...Please do not power off! 10% Completed"
3) "Failed to recover ME Firmware..."
但这是正常的，现阶段系统还没有意识到我在fwupdmgr reinstall命令中要求的改变的存在。
之后，它经过了启动画面，然后屏幕保持黑色大约 1-2 分钟。
最后在左上角打印“系统重置”。
然后它又重启了。这次一切正常。
现在一切正常。
