IOError: [Errno Invalid input device (no default output device)] -9996 #257

Hello everyone, I'm trying to configure snowboy on my rpi3 to replace the "OK Google" hotword. After configuration I'm running before the google assistant and soon after snowboy command.

I obtain this issue:

Traceback (most recent call last):
  File "/home/pi/snowboy/wakeword.py", line 26, in <module>
    detector = snowboydecoder.HotwordDetector(model, sensitivity=0.5)
  File "/home/pi/snowboy/snowboydecoder.py", line 116, in __init__
    stream_callback=audio_callback)
  File "/usr/lib/python2.7/dist-packages/pyaudio.py", line 747, in open
    stream = Stream(self, *args, **kwargs)
  File "/usr/lib/python2.7/dist-packages/pyaudio.py", line 442, in __init__
    self._stream = pa.open(**arguments)
IOError: [Errno Invalid input device (no default output device)] -9996

if I launch it without launch google assistant first, snowboy is running fine and the hotword is detected fine.

Can you help me to fix this pls?

Could you post your audio configuration? I'm having the same problem.

For future searchers, I found https://github.com/shivasiddharth/GassistPi/blob/a47a02231aa23af9d53a004bbec1f474ca18fec2/audio-drivers/USB-MIC-HDMI/scripts/asound.conf to be almost exactly what I wanted. I just needed to change the hw numbers.
