Installation

pip install -r requirements.txt
sudo apt install libportaudio2

You will also need the audio_common_msgs package.

Usage

If you are unsure what device to use, you can run the following command to list all available devices:

ros2 run norlab_audio_py audio_driver

It will fail with a similar message:

[audio_driver-1] ValueError: Multiple input devices found for '':
[audio_driver-1] [0] ATR4650-USB: USB Audio (hw:0,0), ALSA
[audio_driver-1] [1] ATR4650-USB: USB Audio (hw:1,0), ALSA
[audio_driver-1] [2] HDA Intel PCH: ALC888-VD Analog (hw:2,0), ALSA

In this case, you can specify the device you want to use by filling the device parameter with one of the three connected device:

/**:
  audio_capture:
    ros__parameters:
      device: "hw:0,0"
