That dtoverlay was for the octo card, you will want to use a different 
one for your card if it isn't an octo.

For the original stereo and zero cards :

dtoverlay=audioinjector-wm8731-audio

For the ultra card :

dtoverlay=audioinjector-ultra


For the soon to come Isolated DAC and ADC (I expect it will be) :

dtoverlay=audioinjector-isolated-soundcard
