我有一台 Lenovo IdeaPad 14ARE05，并在其上安装了 Debian SID。 pulvac 中未检测到内部麦克风。经过大量谷歌搜索后，我发现我的问题与这。然而，当该解决方案发布时，内核 5.8 刚刚发布。现在 Debian 默认有 5.10。尽管如此，所需的驱动程序snd_rn_pci_acp3x在 中仍然不可见modprobe。有办法安装吗？
编辑：麦克风在 Ubuntu Live USB 中工作
编辑：这些可能有帮助

您的麦克风应该可以linux-image-5.9.0-0.bpo.5-amd64-unsigned在安装了 Linux 映像的debian Buster 上工作buster-backports。
在 debian Sid 上你应该已经linux-image-5.10.0-1-amd64或linux-image-5.10.0-1-amd64-unsigned安装了
加载驱动程序：
sudo modprobe -v snd-rn-pci-acp3x
