I have been using the ADAU1452 for years.
Sigma Studio has a serious bug in NxM Mixer.
I confirmed using Sigma Studio version 3.17, but the result was the same.
Bugs in the NxM Mixer vary with the number of inputs and outputs.
For example, in the 14x4 NxM Mixer, after setting all levels to -200, adjust the 1x2 level to 0dB as shown in the figure, so you can see the signals at 1 and 2 outputs.
Because of this bug, whenever I use the NxM mixer, I have to check all Input / Output every time.
Please fix this problem.

Hi Gundang:

We apologize and will look into fixing this bug ASAP, in the mean time can I suggest that you use the audio Signal Router:

Please comment.

Hello Gundang,

I have tested this with a 4x4 mixer and so far it is working fine.

Can you attach your project?

Also, which revision of SigmaStudio are you using?

Thanks,

Dave T
