ADAU1442 Input ASRC Clock problem

Hello everyone!

 

we are currently setting up the ADAU1442 on a new board. Input is 4x I²s on Input 0-3. All are slave to input clock domain 0.

 

If we set the i²s input to ASRC input, the ASRC seems always to use spdif input clock instead of input clock domain 0 (although it is set to "slave to clock domain 0" in the serial io). If spdif in is connected (same source as the I²S) everything fine; otherwise looks like lost clock.

 

Any suggestions?

 

Thanks

Ron
