Audio keeps on looping

Hey  

 

I`m a beginner at working with the altera FPGA de2 board and I need some advice. 

Currently i´m trying to read an audio sample and change it into an echo in C. 

I got the line in and line out working, but the problem now is that i´m always getting an output(it´s looping) before running the C code. 

What i want is that I only get an audioinput when I ask it and send it to the line out in the NIOS II C. 

I don't know if this is something i need to do in quartus VHDL or in C. 

Can somebody help me? 

 

Greetings, 

 

Jack
