Hello Magnus,

Sorry for the delay. I had no idea this was a question about the ADAU1701.

How is it used on the JAB5? I guess I need to look this up?

I will need to see the schematic and it would be handy to have a copy of your project.

I suspect this is a sampling rate issue.

Hi Dave,

The JAB5 has an integrated ADAU1701.

I'm attaching my project.

I also have a DIPO2 connected via I2S.
