#The below 2 sections are commented, they control the default sound card to use
#This set up is for a Pi with an I2S microphone attached using the guide
#from adafruit at
#Uncomment and the I2S will be your default card (assuming same setup)
#but you won't get audio playback because both recording and playback will be
#TODO - Figure out how to set default for recording separately
#To adjust use aplay -l to work out the devices you have and their card number
#For recording devices use arecord -l
