This error will come up if no audio devices are detected.
- Make sure the audio device was installed correctly
- Verify the audio device is plugged into the computer
- Download and install the latest updates to audio device drivers
In Vista and Windows 7 go to control panel > Hardware and Sound > Sound > Recording tab and right click to show disabled devices. Enable any devices that might be disabled.
之後就好了。
爲了在錄製時不出現麥克風的噪聲，
只是想錄制系統聲音，
