I2C Problem on DE2

Hallo, 

 

I am developing a NIOS2-System on the DE2-Board, using the latest Quartus, SOPC, NIOS2 IDE and the University_Program_IP_Cores_90. Anything works ok, but i have troubles with the Audio/Video Core. The automatic and the manual configurations of the audiochip with the Audio/Video Configuration Core do not work. I tried the configuration using Microtronix Avalon I2C module and it seems the I2C is working, but does not get an acknowledge from the slave. Any idea what is going wrong? 

 

Thanks, 

Peter
