我有一个zoom会议托管在 Microsoft Surface 平板电脑上。
zoom这台运行 Ubuntu 的笔记本电脑已通过 Web 界面（使用）加入会议firefox。这台笔记本电脑名为 Gondor，运行的是groovy20.10。
在刚铎笔记本电脑上，我收到一条消息：
“您的浏览器阻止访问您的麦克风。”
我没有确定麦克风正在使用这台笔记本电脑。如何允许访问麦克风？
在浏览器中，我点击一个按钮来停止阻止麦克风，但仍然看到上述消息，zoom表明浏览器阻止访问麦克风。

更新：
戴尔笔记本电脑（gondor）上的麦克风肯定作品使用textnow它值得的。
由于我没有做任何更改，所以我认为这是特定于或关于zoom其本身的事情。笔记本电脑上的麦克风效果很差，但可用于测试目的。
