Ubuntu 20.04 IEC958/SPDIF/光纤音频无声音

我是 Linux 新手，正在运行 Ubuntu 20.04。我正在使用 MSI 主板，使用光纤音频线时听不到任何声音输出。

我尝试使用：

sudo aplay -l

并得到以下输出：

我认为我的声卡已被识别（ALC1220VBDT）

我还尝试调整声音设置、Alsamixer 和 Pulse Audio 的设置。

阿尔萨混音器

声音设置

脉冲音频

我看到声音通过混音器输出，但听不到任何声音。我尝试重新安装 alsamixer 和 pulse audio，但没有成功。我还尝试使用有线耳机，但没有听到任何声音。如果我可以提供有关我的配置的更多信息，请告诉我。任何建议都会有所帮助。谢谢
