Hi, I'm trying to do a similar program with Audio IP core but I am using the the latest University IP audio core ==> "altera_up_avalon_audio.h".

The problem I am having is that before I execute my code on Nios, I connect my 3.55 mm audio cable from my PC to the MIC or LineIn port and I am able to listen from earphones what the PC's audio out is from the audio out of the board without executing the code on Nios. This occurs right after I compile and run the board. Does anyone have ideas?

Also, I was wondering foleyme, what component you used to develop with just the normal "alt_up_audio.h".

Thanks,

Charlton
