想知道是否可以将 VLC/Viber 的音频输出发送到耳机，将 Clementine/Amarok 的输出发送到笔记本电脑扬声器

Question

我在 HP Envy 15 上使用 Kubuntu 16.04，其规格如下：

00:00.0 Host bridge: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor DRAM Controller (rev 06)

00:01.0 PCI bridge: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor PCI Express x16 Controller (rev 06)

0f:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0c)

这台笔记本电脑预装了 Windows 8.1（显然，现在人们不能不支付微软税就购买电脑，不是吗？）在我清除它并在其上安装 Kubuntu 14.04 之前，我注意到我可以将各个应用程序组（视频、音乐、通信）的输出定向到笔记本电脑的扬声器或耳机。我认为这是一个非常巧妙的技巧。

在 Kubuntu 16.04 中，从 KDE Plasma 5 桌面系统设置的多媒体模块，我可以执行类似操作，但有一个注意事项，虽然它允许我在 HDMI 输出、内置输出和蓝牙设备之间进行选择，但它将耳机和笔记本电脑内置扬声器捆绑在一起，放在一个条目中，因此我可以例如将 Viber 的输出发送到内置输出，将 VLC 的音频输出发送到 HDMI，将 Amarok 的音频输出发送到蓝牙扬声器，但如果连接了耳机，我就无法将任何输出发送到笔记本电脑的内置扬声器。有什么可能的解决方法吗？

任何帮助都将非常感激。
