We are using the Mini-DSP in the AIC3262 codec. We have noticed that after powering on/off the DAC a number of times we lose the sound. When checking the DAC Mini-DSP Instruction map we could see that it been partly cleared (set to zero). We get this effect just by powering on/off the DAC. More and more addresses in the instruction map is set to zero and after a while the Mini-DSP stops working.
What could be the problem?
