![Presonus 44VSL 无法从前置左扬声器输出播放](https://linux22.com/image/1200144/Presonus%2044VSL%20%E6%97%A0%E6%B3%95%E4%BB%8E%E5%89%8D%E7%BD%AE%E5%B7%A6%E6%89%AC%E5%A3%B0%E5%99%A8%E8%BE%93%E5%87%BA%E6%92%AD%E6%94%BE.png)
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。
