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

  • 772

我有一个带有 (x)Ubuntu 16.04 的 Skylake 系统 (ASRock Z170 Gaming-ITX/ac)。

我的扬声器是通过 SPDIF 端口连接的，但是有问题。

当我检查音频配置文件（在 中pavucontrol）时，我看到它Analog Stereo Output (unplugged)已被选中。即使此配置文件错误，扬声器也会定期播放，但音量无法正常工作 - 任何高于静音的操作都会导致扬声器以最大音量播放。

如果我选择Digital Stereo (IEC958)，扬声器根本不会收到任何信号。

我怎样才能解决这个问题？
