ADAU1761 - MicroControler - Index Selectable Filter problem

Hi everyone,

I program my DSPs using a microcontroler for bootup.

When I try to select my Filter ( in the Index Selectable Filter block) with the index using a DC source, the index 0 and 1 work fine but then afterwards only every 2 times I change the index it works... it is very weird. I wasn't able to do a fix within my program (to patch this once in two times thing).

I also tried reducing my number of filters and it didn't help.

Booting up from SigmaStudio, I don't have this problem.

Is it related to safeload or something? It shouldn't be since it is a DC source controlling the rest...

Any help is appreciated, thanks!
