从 20.04 升级后，声卡不再被识别

从 20.04 升级后，声卡不再被识别

Dell Precision 5750，20.04 时声音运行正常。

但是，当我升级到 20.10 时，系统停止识别我的声卡，进一步升级到 21.04 也没有任何变化。强制重新加载/重新安装 alsa 也没有用。

声音设置将“虚拟输出”显示为输出设备。

Alsamixer 仅将 HDA Nvidia 视为 HDMI 的声卡。“aplay -l”也是如此：

所以我推测我的卡是板载 Intel Realtek 的，它应该使用 snd_hda_intel 驱动程序。我还仔细检查了它是否在 BIOS 中打开。

有什么想法下一步该看哪里吗？

答案1

尝试

$ sudo apt-get install linux-modules-extra-$(uname -r)

同时发布输出

$ modprobe --show-depends snd_hda_intel

在问题中

答案2

已经尝试安装 linux-modules-extra，说它已经是最新版本。

我也尝试查看依赖项，但是通过以下输出无法真正判断哪些已安装、哪些未安装：

insmod /lib/modules/5.11.0-17-generic/kernel/sound/soundcore.ko 
install /sbin/modprobe --ignore-install snd $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-ioctl32 ; /sbin/modprobe --quiet --use-blacklist snd-seq ; } 
insmod /lib/modules/5.11.0-17-generic/kernel/sound/core/snd-timer.ko
