我是 Linux 新手，我在笔记本电脑上添加了 PreSonus 44VSL。除了一个输出扬声器外，其他一切都运行正常。我进入声音系统设置并选择 PreSonus，然后单击测试按钮。我使用了一个扬声器并将其插入 PreSonus 上的输出插孔，然后单击测试屏幕上的每个扬声器以查看每个输出插孔映射到什么。结果如下。
输出插孔 1：前右<<应为前左
输出插孔 2：前右
输出插孔 3：后左
输出插孔 4：后右
我使用的是 Ubuntu 22.04，不知道在哪里查找或如何修复此问题。任何帮助都将不胜感激。我运行了以下命令，但输出没有任何异常。如果有人感兴趣，我还有一个 alsa-info 的详细列表可以添加。
