Tool/software:

I am developing a project with PCM5122. The PCM5122 has no output after selecting "Fixed process flow" as like "PCM5121: PCM5121 has no output after selecting Fixed process flow with configurable parameters".

PCM5121: PCM5121 has no output after selecting Fixed process flow with configurable parameters. - Audio forum - Audio - TI E2E support forums

I don't have a PCM5122EVM.

In the above topic, Xp Zheng said, "Yesterday I received the EVM board, and through PurePath Studio I know how to write the sound effect parameters correctly."

I want to know what it is.

I want to know what is wrong with my source code. And I don't know how to set up registers Reg 8 to Reg 47 on Page 44.
