I tried to just open some of the sample code because I really want to write my code in python.  But when I try to run the listen.py sample I get the following error

Hi Pamela,
Dont worry, this is not an error. As our board ( Arduino Board ) have an special Sound Card, the Alsa drivers try to connect first with the Raspberry Pi3 Sound Card and there is not possible due is captured by our own card firstly.

But due to this error the python code is not working. Can you please suggest a solution, some modification that I should make for it to work?
