sudo apt-get install python-dev python3-pyaudio python-pyaudio-doc
sudo ln -s /usr/lib/x86_64-linux-gnu/libportaudio.so.2 /usr/lib/x86_64-linux-gnu/libportaudio.so

. ~/ve_amodem/bin/activate
pip install wheel
python setup.py bdist_wheel 
pip install .

You can also use --audio-library libportaudio.so.2 flag to specify the PortAudio shared object to be used.

If you have aplay and arecord installed (e.g. via https://packages.debian.org/stable/alsa-utils), you can also use --audio-library ALSA:

$ amodem send -c -vv --audio-library ALSA
