Biquad settings not working with Optical input

Part Number: PCM5242RHBEVM
Other Parts Discussed in Thread: PCM5242

Hello,  I hope someone can help me out.

Using the PCM5242 EVAL board.  

Example 1; Loading the HybridFlow 4 and using the USB input, when I adjust the Biquads under Audio Processing it works fine.  For example; a Linkwitz Low Pass, set at 100Hz.  I get the expected results acoustically.

Example 2; Then change to the Optical input and move the jumper, sample rate 44.1kHz.  When I set the same Low pass filter, I get full range output. The Low Pass filter does not change the audio output anymore.

Is there a step I'm missing to make it work?   Also I would say Pure Path 2 console and the PCM5242 EVAL board using example 1 does not really seem stable on my computer as well.  It has locked up a couple of times.   

On a unrelated note....Pure Path 3 console and the supported EVAL boards for that which I have used, works fine.
