Troubleshooting: DeviceNotFoundException

Example

signalflow.DeviceNotFoundException: Could not find device name: Scarlett 2i2

This exception occurs because the audio device specified in the configuration could not be found, or no audio devices at all could be found.

Check that the device name that you have selected exists, and is connected to your computer and powered on.

SignalFlow selects its output device based on the device that you have selected in your ~/.signalflow/config, in the environmental variable SIGNALFLOW_OUTPUT_DEVICE_NAME (or SIGNALFLOW_INPUT_DEVICE_NAME for input devices), or in the config property passed to the AudioGraph
A list of all available devices can be found by running the terminal command signalflow list-output-device-names
```
[audio]
output_buffer_size = 8192
```
