我有一台 USB SteelSeries 9H，配有自己的声卡。它在 16.04 上默认可以工作，但升级后就不能用了。
当我插入并执行它们时cat /proc/asound/cards我得到
0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xd3710000 irq 31
1 [Headset ]: USB-Audio - SteelSeries SC2 USB Headset
SteelSeries SteelSeries SC2 USB Headset at usb-0000:00:14.0-3, full speed
我卸载了 alsmixer 和 pulsaudio，尝试运行 alsmixer 并将耳机（它们在那里可见）设置为默认使用，但我得到了
cannot load mixer controls: Invalid argument
在 Ubuntu 的选项下Sound，耳机根本看不到。但是如果我通过插孔（非 USB）插入任何其他耳机，它们都可以正常工作。
尽管如此，如果我在运行时将它们插入dmesg --follow，我可以看到系统检测到它们。下面的日志

有人对如何解决这个问题有什么建议吗？
答案1
尝试之后aplay -L我得出结论，这只是一个软问题。
有人推荐帕武控制。借助这个小工具，我能够解决问题并重新启用我的耳机。
