On Linux, please make sure libsndfile is installed, e.g. sudo apt-get install libsndfile-dev
PySpaTools can also be used to play audio to audio device. To enable that we need to have pya and PyAudio installed. Please follow this links to install the dependencies: https://github.com/interactive-sonification/pya
Usage:
from pyspatools.playback import play, device_info
devices = device_info() # Here you can find a dict of all devices available. Pick the index
idx = 0 # Replace with the index you want, or do a name match from devices
inputs = [as1, as2, as3] # A list of AudioSignal
chs = [1, 2, 1] # A list channels that each input is supposed to be played on. For stereo, use [as1, as1], [1, 2] as inputs and chs
play(inputs, chs, device_index=idx)
