OSError: No Default Input Device Available

ambarmendez commented 5 years ago

Steps to reproduce

Everything started when trying out the installation of the package with

python -m speech_recognition

Then, execute the following commands:

sudo apt-get install portaudio19-dev python-all-dev python3-all-dev
sudo apt-get install python-pyaudio python3-pyaudio
conda install -c conda-forge portaudio
conda install -c anaconda pyaudio

Despite having installed PyAudio, because of the microphone, got another error:

Traceback (most recent call last):

device_index = pa.get_default_input_device()
OSError: No Default Input Device Available

Expected behaviour

A moment of silence, please...
Set minimum energy threshold to 600.4452854381937
Say something!

Actual behaviour

It does not detect any default microphone even though there is just one input device working properly because it was tested by executing the commands arecord and then aplay.

python -c "import speech_recognition as sr;print(sr.Microphone.list_microphone_names())"
[]
