occasional audio noise when powering up ADAU1467

stmoeller60 on Dec 4, 2020

I have downloaded a huge program to the ADAU1467 and during selfboot

occasionally I get a short loud audio noise when powering up the ADAU1467.

Can someone give me a simple advice what to do in the sigmastudio ( Hibernate ? )

Does this occur, by any chance, when there is an active S/PDIF input? Is there a trimmed down project you can share that does this?

I'm only using the analog AD Input and DA outputs. It's only happening with this huge project.
