Linux下配置USB数字麦克风

Linux下配置USB数字麦克风

我刚买了一个数字USB麦克风。它看起来不错,但我无法让它发挥作用。我使用的是openSuse 12.3。

我如何知道我的系统是否有此类麦克风的驱动程序?

好消息是它alsamixer是一个 USB 麦克风。它被设置为全音量捕获设备,它已列出,arecord --list-devices但我仍然无法开始录制arecord hw:N,M;我得到一个静音文件 test.wav。

据我了解,第一步应该是禁用所有第三方声音服务器(如 Pulse-Audio、Xine、Phonon 等)并尝试 ALSA 方式。

arecord --list-devices出行:

 card 1: MICROPHONE [USB MICROPHONE], device 0: USB Audio [USB Audio]  
 Subdevices: 1/1   Subdevice #0: subdevice #0

我尝试用 进行录音audacity,但是没有任何效果。

dmesg 命令输出:

这是什么意思 :
