我有一个较旧的 Mackie Big Knob Studio，使用它时它在我的音频输出列表中显示正常。我的旧设备停止工作，我换了一个新的。现在这个没有显示在设置菜单的列表中。
Linux 信息：
Distributor ID: Ubuntu
Description: Ubuntu 22.04.2 LTS
Release: 22.04
Codename: jammy
如果我运行，aplay -l我会在下面的输出中看到它：
card 1: STUDIO [BIG KNOB STUDIO], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
我更换了 USB 端口，但情况仍然一样。
这之前在 Ubuntu 上运行得很好。任何音频提示都会有帮助，因此我可以在设置中选择它作为输出。
任何帮助都将非常有帮助！
