Cyclone II starter dev kit,DE1, Audio HELP!

Hi Everyone,  

 

I'm using the DE1 FPGA board. I'm trying to pass a signal from the mic to the speaker using the UP IP. The zip file and related pdf can be found here: http://www.altera.com/education/univ/materials/ip-cores/unv-ip-cores.html  

 

I was successful in putting this in the provided reference design.  

 

:confused: Problem: The fifospace is always empty and cannot be enabled. This creates further problems b/c then the mic isn't reading into the ADC buffer.  

We also need to write to the speakers.  

 

Command used for mic: alt_up_audio_read_left_channel() 

Command used for the speaker: alt_up_audio_write_left_channel 

 

The problem appears not to be with the code. 

 

If anyone can help me, that would be awesome! :D
