我在我的电脑上安装了 Ubuntu 20.04 LTS，最终决定不再使用 Windows！:) 无论如何，除了一件事之外，一切都很好。我无法从主板上的内置声卡中获得任何声音。我正在使用 MSI B450 TOMAHAWK MAX II MB，它看起来像是 Realtek® ALC892/ALC897 编解码器支持。不确定它实际上是什么芯片。我看过其他文章，但无法解决它。有什么线索吗？下面是一些转储，但我太菜鸟了，不知道该怎么做。

同样的问题，我不得不采取一种非传统的方法，我的显示器没有扬声器，所以我买了一个便宜的 HDMI 音频分配盒，将主板的 HDMI 输出连接到分配盒，将盒子的 HDMI 输出连接到显示器，最后将扬声器连接到分配盒的音频输出，然后就可以正常工作了。
花了好几天时间尝试网络上的所有技巧来通过软件解决这个问题，但从来没有奏效，Ubuntu 从来没有识别过该卡，“声音系统设置”总是说“DUMMY OUTPUT”，让我抓狂......
