Hi Gerhard,
Glad to hear it! The instructions for win7 drivers will be added in that update.
Well, let me understand a little bit more about what you are trying to do. What is the input for your system? Are you using ADC or DAC filters? What coefficients are you using? And, how are you verifying the success/failure?
Just as a note (assuming you are using the GUI), the filter coefficients aren't loaded onto the TLV320AIC3104 until you press the "Download Coefficients" button.
Regards,
