Youtube 仅在 Ubuntu 18.04 中缓冲

我最近从 16.04 升级到了 18.04，除了不能再观看 YouTube 之外，其他一切都很好。无论是在 Firefox 还是 Chrome 中，我得到的都是黑屏，缓冲符号不停地旋转。
不过 Netflix 和其他流媒体服务似乎没问题。

没有错误消息，没有信息。以下是来自 YouTube 的一些调试信息：

答案1

您的计算机是否连接了扬声器/耳机？如果没有，请尝试连接耳机或扬声器。当扬声器/耳机未连接时，我也遇到了完全相同的问题，因此这可能是与音频不可用有关的问题。

注意：我的 ubuntu 在 vi​​rtualbox VM 中运行。

答案2

当我从 Ubuntu 16.04 升级到 18.04 时也遇到了这个问题，在我做了一些小改动之后问题就解决了。

我关闭了跨源读取阻止 (CORB) 扩展，跨源读取阻止 (CORB) 是一种算法，可以在可疑的跨源资源加载到达网页之前识别并阻止它们。CORB 通过将敏感数据远离跨源网页来降低泄露敏感数据的风险。

在大多数浏览器中，它将这些数据保留在不受信任的脚本执行上下文之外。在具有场地隔离，它可以将这些数据完全排除在不受信任的渲染器进程之外，甚至有助于抵御 Spectre 等旁道攻击。这适用于 Chrome 和 Firefox。然后一切看起来都很好。
