Tone control implementation

Category: Software
Product Number: ADAU
Software Version: SigmaDSP 4.7

I, too, am trying to implement a simple tone control. The strategy described here, using indexed filters, seems very straightforward, but it hasn't worked in my hands.

As best I can tell, I have the correct number formats. However, no sound passes through the system. Using the Stimulus/Probe pair, I can see the signal after the first T-Connector, but when I look after the output of the indexed filters, there is no signal present. I have tried using a variety of DSP read backs, and the numerical inputs to the filters appear to be intact (the numbers are displayed as though they are floats, but they tae on integer values (1.00000, 5.00000, etc...)

Might someone tell me what I'm doing wrong here?

Thanks so much for the support.
