ADAU1452 ADIsurround1 virtual surround

Hello ,ADI experts，

My costermer wants to test adisurround 1 of adau1452（virtual surround ）。

Sigmastudio version is 4.15,

But the results：

It sounds like the left and right channels are mixed together, not separated. The same is true for left and right surround sound。

But the effect of virtual surround sound is still there，Is this normal?

Remove the adisurround1 module, change to stereo output, channel immediately separated。why?

Best regard!
