在 Skype 和录音机应用程序中，我都无法从内置麦克风中捕获任何音频。我不知道为什么。否则，声音输出运行良好。
我也尝试运行gstreamer-properties并将默认输入插件设置为 PulseAUdio（以匹配输出），但没有帮助。
我尝试运行alsamixer -V all但只得到 2 个与输入相关的条目：Capture(L R)设置为 100 且未静音（也不可能），以及Analog Mic Boost设置为 20db。
额外信息：相机（视频）在 Skype 和 Kamerka 上运行良好。
你能帮我让我的麦克风工作吗？

答案1
我有一台联想 IdeaPad R580-3087，配有相同的声卡（英特尔公司 Panther Point 高清晰度音频控制器，版本 04）。我试过使用，gstreamer-properties但没有效果。然而，在搜索解决方案时，我读到在内核更新到较新版本后麦克风停止工作，因此使用此安装版本 3.5内核升级指南。
现在我可以使用 gnome-sound-recorder 录制声音，Skype 通话测试但gnome-control-center sound它仍然看起来被禁用，好像没有麦克风。这可能是因为gstreamer-properties我已将设置从自定义更改为 PulseAudio，并且在pavucontrol“输入”选项卡下，麦克风似乎显示为工作约 3 秒钟，但我仍然可以录制声音或使用 Skype。
所以我不知道为什么它看起来不起作用，但实际上却起作用了。所以我至少可以使用 Skype 和其他录制媒体。如果有人有更多信息，我将不胜感激。

添加以下行对/etc/modprobe.d/alsa-base.conf我有帮助，也可能对您有帮助：
options snd-hda-intel model=auto
