Hi, I have two Matrix creator boards which I bought together. I am trying the Alexa python demo on each of them http://www.instructables.com/id/Build-DIY-Amazon-Alexa-With-a-MATRIX-Creator-on-Ha/.
While I am able to run it one one board, the other seems to get stuck while looking for a microphone. I also tried recording with ‘arecord’, and it seems to have the same behavior. The presumable ‘faulty’ board gets stuck on calling ‘arecord’, while the other board starts the recording.
I also notice that the ‘faulty’ board does not have the D50 led on, while the other one has. Does this point to any hardware problem with the board? Or is it some other issue which can be fixed at a software level?
