Citrix Workspace 应用程序 2009 网络摄像头和麦克风无法在 Ubuntu 20.04 上运行

  • 772

我安装了适用于 Linux 的 Citrix Workspace 应用程序 2009（deb 包）。和缩放插件。它工作正常，多显示器等。当我在 Citrix 会话（Windows 10）中连接到 Zoom 呼叫时，它显示一帧视频，然后视频冻结（我听到网络摄像头中的继电器点击，然后再次关闭）。

我可以看到这是/var/log/syslog，每秒重复一次：

Windows 10 摄像头应用程序表示未检测到摄像头，所以我猜测视频是通过 TCP 从本地 Citrix Zoom 插件流式传输的。

感谢任何想法，我无法在本地从 Citrix 或 Zoom 获得更多有用的信息。

    我有同样的问题。原来我使用了错误版本的 Zoom VDI 插件。我的虚拟桌面上的缩放版本是 5.0.23901.6522。在这种情况下，我必须安装插件的 3.0.5 (5.0.469977.0929) 版本。
