ADAU1466 SPDIF receiver at 192K rate

I'm working on ADAU1466 running at START PULSE rate of 192K for a wide band application (24576K external clock ref).

I'm not able to receive a digital SPDIF stream at 192K rate.

I've configured the ASRC0 for this purpose, connected to SPDIF input receiver.

I see that ASRC0 ratio in some case is not fixed to 0x1000 but oscillate around this value

For others rate no problem but only for 192K

Any suggestions?

Thanks in advance
