Citrix Workspace 应用程序 2009 网络摄像头和麦克风在 Ubuntu 20.04 上无法使用

Citrix Workspace 应用程序 2009 网络摄像头和麦克风在 Ubuntu 20.04 上无法使用

我安装了适用于 Linux 的 Citrix Workspace 应用程序 2009(deb 包)。还有 Zoom 插件。它运行良好,支持多显示器等。当我在 Citrix 会话(Windows 10)中连接到 Zoom 呼叫时,它会显示一帧视频,然后视频会冻结(我听到网络摄像头中的继电器打开,然后再次关闭)。

我可以看到这是/var/log/syslog每秒重复一次的:

Windows 10 相机应用程序显示未检测到相机,因此我猜测视频是通过 TCP 从本地 Citrix Zoom 插件流式传输的。

任何想法都值得赞赏,我无法从本地 Citrix 或 Zoom 获取更多有用的信息。

我遇到了同样的问题。原来我使用了错误版本的 Zoom VDI 插件。我的虚拟桌面上的 zoom 版本是 5.0.23901.6522。在这种情况下,我必须安装该插件的 3.0.5 版本(5.0.469977.0929)。
