请问HN：为什么Facebook.com会激活麦克风？
在macOS的Safari浏览器中访问Facebook动态时，菜单栏会出现系统麦克风活动图标，并显示Safari正在使用它。我并没有授予权限。当我询问ChatGPT时，它说“即使用户没有授予麦克风权限，Safari仍会创建一个音频捕获会话，以进行能力协商，但在获得权限之前，没有音频数据会离开设备。”——这准确吗？

In Safari on macOS when visiting the Facebook newsfeed, the system mic active icon appears in the menu bar and says that Safari is using it.<p>I haven't granted permission. When I asked ChatGPT it said 'Safari creates an audio capture session even if the user has not granted microphone permission, for capability negotiation, but no audio data leaves the device until permission is granted.' - is that accurate?
