Hi, Please help me with the below issue, I am using Matrix Creator along with Raspi3 [Jessie Pixel]

When i was trying to run the Microphone test recorder , i was getting 8 Audio streams as RAW and after converting them to WAC when i tried to play the Channel 0 Audio track using aplay it was total Silent.

All the other wav tracks were having noises like "GRRR" . Am i missing something here ?

  1. Is there any steps i need to do with ALSA Mixer ?
  2. Should i need to replace any file configurations in Raspbian to map the Microphones..

I really think that the Documentation can be little improved and i will also be happy to contribute on the Documentation if i was able to success fully run this sample.

Kindly help me, since i am gonna procure more devices based upon this experiment, thanks

Regards JK
