7) Connect an audio cable from a CD player, microphone, or other

audio device to the EVM board’s Audio Line In Connector 3.5 mm
stereo jack P10.

8) Connect an audio cable from a speaker to the EVM board’s Audio

Line Out Connector 3.5 mm stereo jack P13.

9) Use the provided USB cable to connect the EVM's USB connector to

a PC. You may want to connect through a USB hub for safety. The
USB connection enables debugging via Code Composer Studio.
