我刚刚使用此映像全新安装了 Lubuntu：lubuntu-22.04.4-desktop-amd64.iso。一切正常，除了音频，根本没有声音。
系统托盘中有一个扬声器音量图标。
计算机是新的（顺便说一下，显示器也是新的），音频尚未测试。
AlsaMixer 报告了两个声音适配器：ATI R6xx HDMI 和 Realtek ALC897。计算机通过标准音频线以及通过 HDMI 和 KVM 切换器连接到显示器。
主板是MSI A520M-A PRO，CPU是AMD Ryzen 5 5600G。
提前致谢！
附加数据：我尝试过这个：
sudo lshw -C sound
并得到以下结果：

我认为问题在于选择合适的音频驱动程序，但我无法做到这一点。
