我尝试了所有能在网上找到的方法，但还是无能为力。HyperX Cloud Flight S 耳机不允许我使用麦克风，而之前的非 S 版本却运行正常。以下是一些相关输出：

这内核更新在 5.7rc3 中引入了针对此问题的补丁（专门针对此耳机）。修补后，您的 dmesg 输出应该有一行如下内容：
[ 6.804026] kernel: usb 1-1: Found post-registration device assignment: 095116ea:02
alsa配置文档说明：
Module snd-usb-audio
--------------------
...
delayed_register
The option is needed for devices that have multiple streams
defined in multiple USB interfaces. The driver may invoke
registrations multiple times (once per interface) and this may
lead to the insufficient device enumeration.
This option receives an array of strings, and you can pass
ID:INTERFACE like ``0123abcd:4`` for performing the delayed
registration to the given device. In this example, when a USB
device 0123:abcd is probed, the driver waits the registration
until the USB interface 4 gets probed.
The driver prints a message like "Found post-registration device
assignment: 1234abcd:04" for such a device, so that user can
notice the need.
因此，利用从 dmesg 获取的上述信息以及从配置文档中获取所需的字段，将其添加到 alsa-base.conf 的末尾
# Add delayed register for HyperX Cloud Flight S Headset
options snd-usb-audio delayed_register=095116ea:02
然后重新启动，您应该能够看到预期的耳机和配置文件。
顺便提一下，snd-usb-audio 模块中还有另一个选项
quirk_alias
Quirk alias list, pass strings like ``0123abcd:5678beef``, which
applies the existing quirk for the device 5678:beef to a new
device 0123:abcd.
这让我相信你可以复制内核 5.4 为“Kingston HyperX AMP”编写的怪癖并将其应用于此耳机，以及添加延迟寄存器，它将在 5.7 之前工作。由于我已经下定决心并进行了内核升级，所以我不会回头检查。如果有人让它工作，请告诉我，我会在这里更新帖子。它应该像以下一样简单：
options snd-usb-audio quirk_alias=095116ea:095116d8 delayed_register=095116ea:02
让我知道！
