No device detected on Linux

On my Linux system, sounddevice does not detect any devices:

import sounddevice as sd
sd.query_devices()

produces an empty output.

My setup: Python: 3.6.0 Name: sounddevice Version: 0.3.7 Name: cffi Version: 1.9.1 Name: PortAudio Version: 19 (installed with anaconda)

On Windows (on the same machine), sounddevice works fine

@danigamba Good to hear that it works now! I hope this problem will be fixed properly by the Anaconda people …

Here is what worked for me on a laptop running Xubuntu 18.04, with a conda-managed python environment:

sudo apt install libportaudio2  # probably it is already installed, but if not this is how to do it
conda install python-sounddevice  # this installed a conda version of portaudio as a dependency
conda uninstall --force portaudio  # the --force flag prevents it from removing sounddevice too

after that sounddevice worked normally.
