如何修复错误的音频配置文件（在 Skylake/Realtek ALC1150 上）？

我有一台 Skylake 系统 (ASRock Z170 Gaming-ITX/ac)，搭载 (x)Ubuntu 16.04。

我的扬声器通过 SPDIF 端口连接，但是出现了问题。

当我检查音频配置文件（在 中pavucontrol）时，我看到 被Analog Stereo Output (unplugged)选中。即使此配置文件错误，扬声器也会正常播放，但音量无法正常工作 - 任何高于静音的设置都会导致扬声器以最大音量播放。

如果我选择Digital Stereo (IEC958)，扬声器将根本不会接收任何信号。

我怎样才能解决这个问题？
