外置声卡 Scarlett 2i2 不播放声音

我有一台第一代 Focusrite Scarlett 2i2，我想在 16.04 上使用它作为声卡。按照说明这里，我安装了 PulseAudio JACK 和 QjackCtl GUI。但是，当我启动 GUI 并检查连接时，我看不到任何类似于 2i2 的东西：

当我运行时，2i2 确实出现了aplay -l && arecord -l：

当我运行时它也会出现lsusb：

我有一个 Logitech 网络摄像头和两个 GTX 660 GPU，这解释了列出的其他一些设备，我不知道它们是否会干扰我连接 2i2 的能力。我不知道接下来该怎么办，因为 2i2 似乎通常都是即插即用的。有什么建议吗？

答案1

在qjackctl 连接，尝试将左侧的 Pulseaudio 插孔接收器连接到最后一个“系统播放”（右侧），这可能是您的 2i2 声卡：
这可以通过从左侧项目拖放到所需的右侧项目来完成，
或者在选择项目后使用“连接”或“断开连接”按钮。
