我只想通过 Chromebox 在全新的 Ubuntu 12.04 ChruBuntu 内核上拨打音频电话。为此，我尝试使用 2 个设备：
罗技耳机H555：http://www.logitech.com/en-au/webcam-communications/internet-headsets-phones/6810
由于这不起作用，我还尝试了网络摄像头，罗技，不确定型号，但似乎是这个：http://mobile.logitech.com/en-us/support/webcams/legacy-devices/3382
最大的问题是它没有显示在我的设置->声音中。
在网上搜索一番后，我了解到 dmesg 可能会有帮助......
有用的输出似乎是这些行：

我仍在搜索很多论坛和博客，但找不到下一步该做什么的答案。
有什么提示吗？

编辑（再次..）
后
gksu gedit /etc/modprobe.d/alsa-base.conf 将选项 snd-usb-audio index=-2 更改为“选项 snd-usb-audio index=1
然后再次插入耳机。
我失去了数字输出并且我的耳机变成了输出：

答案1
在我看来，您正在使用自定义内核，因为输出中列出的 Linux 3.2.7 的uname -a版本号高于当前版本的 12.04 内核 (3.2.0-29)。 (它也低于当前的 12.10 内核)。
查看输出，lsmod我们可以看到没有模块snd_usb_audio 位于已加载模块列表中。您需要使用它来运行大多数使用 USB 音频设备标准的 USB 音频设备。
location 命令列出了几个 snd_usb_audio 模块，但不适用于您正在运行的内核。
我建议您使用标准内核，看看它是否无法检测和支持您的耳机。
如果您自己编译了自定义内核，您可能希望使其工作，我建议通过更改相应的内核配置变量将 snd_usb_audio 设为模块，重新编译内核，然后运行
make modules_install并make install重新安装重新制作的自定义内核。我认识到这个内核可能已将 snd_usb_audio 链接到内核，在这种情况下，我不知道为什么自定义内核没有正确使用它来安装必要的音频设备。
CONFIG_SND_USB=y
CONFIG_SND_USB_AUDIO=m
答案2
根据lsusb -v输出，Linux 内核的 ALSA 子系统 snd_usb_audio 应该为您的设备分配控制和 pcm 设备并驱动它们。
看着这帖子，可能值得尝试该解决方案：
gksu gedit /etc/modprobe.d/alsa-base.conf
改成options snd-usb-audio index=-2`options snd-usb-audio index=1
然后再次插入耳机。
如果这不起作用，请运行 lsmod 并将输出放在您的问题中。
如果 snd-usb-audio 没有出现在列表中，请尝试modprobe snd-usb-audio，并在出现时捕获 /var/log/syslog。同时，请检查 lsmod 和 /proc/asound/devices 以及 /proc/asound/cards 并再次查找接口。
