xiongyihui commented 7 years ago

Is it an error produced by mopidy? run /etc/init.d/mopidy stop to disable it. Could you be able to run arecord or aplay?

xiaooquanwu commented 7 years ago

yes,when disable mopidy or alexa, panic disappear, aplay works ok

xiongyihui commented 7 years ago

If arecord works but alexa does't, it may be a compiling issue of portaudio. We can test it with pyaudio example code

"""PyAudio example: Record a few seconds of audio and save to a WAVE file."""

import pyaudio

CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 2

RECORD_SECONDS = 5
WAVE_OUTPUT_FILENAME = "output.wav"

    frames.append(data)

a compiling issue of portaudio ? how to fix ?

xiongyihui commented 7 years ago

You should rename pyaudio.py, pyaudio is library name and should not be used as your script name.
