如何使我的USB麦克风识别音频控制器？

Question

我正在尝试让USB麦克风在我的Gentoo Linux系统上工作。我能够在lsusb的输出中看到该设备，但我的系统似乎没有将该设备识别为音频控制器。

我正在运行管道，但安装了所有pulseausio、alsa和jack兼容性包。在运行pavucontrol时，我看不到Input选项卡或Configuration选项卡中的麦克风。

lsusb的(相关)输出：

Bus 003 Device 004: ID 1b3f:2008 Generalplus Technology Inc. USB Audio Device

cat /proc/asound/cards的输出：

arecord --list-devices的输出：

当我连接麦克风时，dmesg输出：

Answer 1

结果，当CONFIG_SND_USB_AUDIO被内置到内核中时，我没有更新grub，因此没有使用新的内核。更新grub以使用新内核修复了这个问题。
