alsa-project/alsa-lib issue #13 was edited from paddygoat:

Hello again!

I upgraded Alsa lib to 1.1.7 and tested ok. A small error as below when running in Jupyter Notebook, Python 3.6::

`#inp = alsaaudio.PCM(alsaaudio.PCM_CAPTURE, alsaaudio.PCM_NONBLOCK)
 # UltraMic384K 16bit r0, USB Audio

    inp = alsaaudio.PCM(type = alsaaudio.PCM_CAPTURE, mode=alsaaudio.PCM_NORMAL, device='UltraMic384K 16bit r0')
    # class alsaaudio.PCM(type=PCM_PLAYBACK, mode=PCM_NORMAL, device='default', cardindex=-1)`

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

Thanks!
