Hi, for anyone looking at this post, I found the reply in a different post and I can't find it now, so I'll explain it here (this is the first post that pops out in google)
You need to setup i2s FIRST, make sure there is a clock working, even wait a couple milliseconds, and THEN you configure and initialize the module through L3 or i2c.
Configuration steps:
Sending the commands without the clocks will be rejected by UDA1380, and you will get values different from the expected when you read the registers.
Good luck.
