    An Echo Device using the C.H.I.P. $9 Computer

    Hey Al, I've got a little problem, when I launch main.py, Alexa says "Hello" and at the instant when I press the button, I've got this error :"ALSA lib pcm_params.c:2162:(snd1_pcm_hw_refine_slave) Slave PCM not usableTraceback (most recent call last): File "main.py", line 121, in <module> inp = alsaaudio.PCM(alsaaudio.PCM_CAPTURE, alsaaudio.PCM_NORMAL)alsaaudio.ALSAAudioError: Invalid argument [default]"Do you have an idea how to fix it ?
