Audacity is only recording silence

Causes

• Your microphone gain may be reduced. To fix this, see: Setting recording and playback levels

• 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

• 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.
