Here is an example of a script:
#TLV320AIC12K/14K
#This configuration allows playing audio to the DAC from any media player on
#a computer and recording from the ADC on audio recording software. Pin
#MICIN is configured as the input. The input can be heard via OUTP1/M1 and
#OUTP2/P3 due to the digital sidetone. Audio files played on the computer
#can also be heard via those outputs.
