三星Galaxy Book 3 Pro外接SSD运行Ubuntu 23.04时内置摄像头无法识别

我最近碰到个头疼的问题：我的三星Galaxy Book 3 Pro在外接三星T7 500GB SSD运行Ubuntu 23.04时，内置摄像头完全不被系统识别。不过在本机的Windows 11系统里摄像头是正常工作的，所以应该不是硬件故障。

我已经尝试了不少网上的解决方案，但都没解决问题，具体情况如下：

• 笔记本自带的摄像头物理屏蔽键在Windows下能正常开关摄像头，但在Ubuntu里按了毫无反应，重启系统或者重新打开应用也没用
• 用Cheese和Microsoft Teams测试过，都识别不到内置摄像头，但外接USB-C接口的罗技StreamCam可以正常使用
• 为了排除系统版本问题，我还在另一块外接SSD上装了Ubuntu 22.04测试，结果还是一样识别不到内置摄像头
• 另外还有个独立问题：Ubuntu下声音也没法正常工作，不过这个暂时先不管它

下面是我运行相关诊断命令得到的输出：
