Hi,I'm trying to develop a program with Altera DE2 and Audio IP Core. I declared in memory a wave file just as an array of 32-bits elements. Here it is the code:
alt_up_audio_reset_audio_core(); lw = alt_up_audio_write_left_channel(notify, LEN); rw = alt_up_audio_write_right_channel(notify, LEN); printf ("lw: %d rw: %d\n\n", lw, rw);lw and lr remain stuck to 128,while the array is much longer. it seems the FIFO doesn't empty by itself and the sound is not reproduced. So, how can I make it reproduced?
