It looks like your SOPC project is driven by your PLL. If I understand right, the audio core is in SOPC also.

Here are a few things to try:

Running your system at 50MHz - don't use a PLL to drive your SOPC system and don't use one external to your SOPC system.

If this does not suit your needs, try using the 27MHz clock for your system's PLL. You will still need to bring the 50MHz clock in from the pin directly to your SOPC system.

I hope this helps out.
