Hi,

I am using the adau1761 in a linux environment where I have built my project in sigmastudio and thereafter used the linux fw-tool to generate the binary from the project xml-file.

When I have loaded the dsp binary I also get alsa controls where I can control for instance filter parameters. The issue I am facing is that I get five alsa controls for each filter (b0,b1,b2,a0,a1), which hinders me from updating a filter using safe load since I would need to write all five controls in one go in order to safe load the filter parameters.

As a remedy I have manually patched the xml-file to generate a alsa control which is a 20 bytes hexarray of the five (5*4bytes) alsa controls. This makes safe load work but is cumbersome from a maintenance perspective since when updating the prject I need to manually patch the xml-file.

It would be beneficial if sigma studio could also add filters as a hexarrays in the xml-file, might that feature be possible to include?

Regards,

Danny
