ADAU145x Setting default volume


After browsing the forum I have found, that people have been having a problem with the DSP resetting the volume to maximum after reboot and nobody seems to be answering that question. I just wanted to know, if I implement a rotary volume control, how can I set a "default" volume value (position in the lookup table)? So lets say that I want for the output to be attenuated at -30db at boot-up, is there a way to edit registry values on the EEPROM in such a way that the output starts at -30db and then can be increased/decreased to 0db/-60db respectively? Or is there an easy way to do it in Sigmastudio?
