Amp hat and Matrix Creator on RPi

[chowdhary]

I am trying to get the AMP Hat to work on the RPi. By following your tutorial it works great. But I am using another HAT (http://creator.matrix.one) and when I add the custom $HOME/.asoundrc file the amp hat stops working. I have tried modifying the $HOME/.asoundrc to correspond with the hardware id and device for the amp, but no luck.

.asoundrc:

pcm.!default {
  type asym
  capture.pcm "mic"
  playback.pcm "speaker"
}

pcm.mic {
   type softvol
   slave {
     pcm "array"
   }
   control {
     name "MicArray Master"
        card 0
   }
}

#pcm.speaker {
#  type plug
#  slave {
#    pcm "hw:1,0"
#  }
#}
pcm.speaker {
  type hw
  card 1
  device 0
}

pcm.array {
  type plug
  slave {
    pcm "hw:2,0"
  }
}

aplay -L:
