未检测到内置麦克风 [Lenovo Carbon X1 第 7 代，Ubuntu 19]

Question

更新：本指南的脚本最终对我有用，即使我以前自己单独完成了所有命令。不知道为什么，但想把它扔给其他人阅读。

（作为序言，我在 Linux 方面非常菜鸟，但我已经尝试遵循许多不同论坛的建议，但无济于事。我一直试图提供有关我的系统设置的清晰和必要的信息。）

我买了联想 X1 Carbon 7th Gen 的目的是运行 Ubuntu。当我遇到此处描述的 Wifi 问题时，我决定使用 Ubuntu 19，尽管我更喜欢 LTS 和 Ubuntu 18。系统一切顺利，直到我需要使用麦克风进行 Zoom 通话，当我意识到我的系统没有检测到任何输入设备。看看我的GUI 声音设置是什么样的 - 没有可供选择的输入设备，但我的扬声器正在工作。

在线排除故障后，我发现这个论坛帖子描述了如何在运行 Arch 时解决问题。我决定自己尝试并遵循该指南，因为这个 Lenovo 论坛帖子暗示该指南不是 Arch 特定的，可能适用于其他发行版（例如 Debian、Ubuntu）。但是，即使遵循了指南（考虑到用户 tbw 在回复 #9 中指出的拼写错误，我也无法检测到麦克风。

目前，这就是我的 /etc/modprobe.d/blacklist.conf 的样子。

# blacklist snd_hda_intel
# blacklist snd_soc_skl

当我取消对上述黑名单行的注释时，可用的输入源没有区别，但我无法使用我的扬声器。因此，我暂时对这些行进行了评论。

目前，这就是我的 /etc/pulse/default.pa 的样子。

load-module module-alsa-source device=hw:0,7

这是以下命令的结果。

# ls -l /lib/firmware/intel/sof-tplg/

-rw------- 1 jmarkey jmarkey 32787 Aug 14 13:27 sof-hda-generic.tplg.original

因此，我当前的系统类似于指南的结果。我什至对线程原始帖子的最终编辑中描述的脉冲守护程序进行了编辑，这就是我的 /etc/pulse/daemon.conf 的样子。

enable-lfe-remixing = yes
; lfe-crossover-freq = 0
lfe-crossover-freq = 250

这是有关我的硬件的信息。

如果我应该发布任何其他信息，请告诉我。因为我是菜鸟，不知道上面的信息是不是太多了。

我还尝试了其他一些修复方法，尤其是使用 alsamixer 和 pavucontrol，但无济于事。由于搞乱了这些修复，我的 F4 键后面的灯亮了（表示麦克风被禁用），但我无法通过按下它来关闭它（同时按住 Fn 键和不按住 Fn 键） .

这是以下命令的输出（在黑名单文件中注释了行）。

dmesg | grep sof
[    0.928838] integrity: Loaded X.509 cert 'Microsoft Corporation UEFI CA 2011: 13adbf4309bd82709c8cd54f316ed522988a1bd4'

然后取消注释黑名单行。

\n\n

将以下行添加到/etc/modprobe.d/blacklist.conf：

\n\n

blacklist snd_hda_intel\nblacklist snd_soc_skl\n

\n\n

步骤 4：更新 PulseAudio 配置\n将以下行添加到/etc/pulse/default.pa:

\n\n

load-module module-alsa-sink device=hw:0,0 channels=4\nload-module module-alsa-source device=hw:0,7 channels=4\n
