# Audacity is only recording silence

## Causes

* Your microphone gain may be reduced. To fix this, see: [setting-recording-levels-and-playback-levels](https://support.audacityteam.org/basics/recording-your-voice-and-microphone/setting-recording-levels-and-playback-levels "mention")
* You may be attempting to record a Bluetooth device at an unsupported sample rate. To fix this, see [audacity-records-silence-when-using-a-bluetooth-headset-as-a-recording-device](https://support.audacityteam.org/troubleshooting/solving-recording-problems/audacity-records-silence-when-using-a-bluetooth-headset-as-a-recording-device "mention")
* You may be attempting to record a device which doesn't produce any sound. To fix this, 
  * ensure that all parts of the device are connected properly (cables, microphone, interface, etc), 
  * that microphones in need of phantom power are provided with that,
  * that no mute switches on any devices are turned on,
  * that no faders are turned down, and
  * that an input signal is being produced by the source.
