BF537 VisualDSP volume change app - mic problem

I am a newbie in DSPs and I need to modify the Getting Started example

<install_path>\Blackfin\Examples\ADSP-BF537 EZ-Kit Lite\Getting Started Examples\Part_3_2\TalkThrough_3_2.dpj,

which changes the output volume of an audio file (mp3).

The difference is that i have to change the volume of the microphone, but it doesn`t seem to work, nothing happens, I don`t hear anything in the headphones when I`m using the mic.


Is it because the mic is connected to the line in? (the board doesn`t have a mic input)

Do I have to modify the source code? Is there a solution to make it work?


Thanks in advance!
