设置Raspberry Pi 3 USB麦克风(创意声霸) [英] Set up Raspberry Pi 3 USB mic ( creative sound blaster )

问题描述

有人可以帮助我设置我的RPi 3吗?我想用我的游戏耳机(Creative Technology，Ltd Sound Blaster Tactic(3D)Sigma声卡)建立语音到文本/语音识别的功能.扬声器现在正在工作，但是很遗憾，我无法设置麦克风.

Can someone please help me in setting up my RPi 3. I'm tying to build a speech to text / speech recognition with my gaming headset (Creative Technology, Ltd Sound Blaster Tactic(3D) Sigma sound card). The speakers are now working but unfortunately I'm stuck in setting up the mic.

在我进行设置之前，我可以录制/创建一个wav文件，但是每当播放wav文件时都没有声音.更改某些设置后，我在下面遇到了新错误.预先感谢！

Before i tweaked the settings, I can record/create a wav file but whenever i play the wav file there's no sound. After changing some settings, i'm encountering new error below. Thanks in advance!

错误:

pi@raspberrypi:~ $ arecord -D plughw:0,0 test9.wav

推荐答案

更新

我设法解决了这个问题！事实证明，当我运行alsamixer时，~/.asoundrc配置文件会自动更新.我的配置被新设置覆盖.

I have managed to fix the problem! It turns out that when I run alsamixer, the ~/.asoundrc config file automatically updates. My config were overwritten by the new settings.
