Troubleshooting

Why have I lost sound after connecting a USB device on Windows?

When you connect a USB audio device to a Windows computer, it may automatically become the "default" device that is normally used for both playback and recording. If the USB audio device is not meant as a playback device for the computer (such as a microphone, turntable or tape deck) you may lose sound in Audacity or in most programs on your computer. You can fix the problem as follows.

• Windows Vista and 7: Right-click over the Speaker icon by the system clock, choose Playback Devices, then right-click over the speakers or headphones device you are using, choose "Set as Default Device" and click "OK".
• Windows XP or earlier: Right-click over the Speaker icon by the system clock, choose Adjust Audio Properties, then click on the Audio tab. In the "Sound Playback" panel, click on the downward pointing arrow in the drop-down box, select the inbuilt sound card as the default device and click "OK".

Alternatively, you can disconnect the USB device from the computer after you have finished recording.

Note: To hear audio while you are recording, ensure "Software Playthrough" is "on". This can be toggled on/off by clicking Transport > Software Playthrough (on/off).
