Intel Comet Lake PCH-LP cAVS 声卡，无法为 Linux 内核配置设备

我运行 opensuse Leap-15.2，内核为 5.3.18联想 ThinkPad X1 Yoga Gen 5。我在配置声卡时遇到问题英特尔 Comet Lake PCH-LP cAVS。使用 yast2-gui 配置声音会产生消息

无法加载用于声音支持的内核模块 snd-soc-skl。这可能是由不正确的模块参数引起的，包括无效的 IO 或 IRQ 参数。

部分输出lspci -vv如下

我将非常感谢任何配置设备的帮助。

这是我在此网站上写的第一个回复。当我遇到此错误时，由于此处的某些代码必须编译我自己的内核（此处为 Gentoo 用户），因此我重新编译了内核模块。

这是我的声卡的输出：

还注意到我的系统使用 snd_sof_pci 而不是你的 sof_pci_dev，不知道两者之间的区别，但也许 sof_pci_dev 是“前沿”
