    Yep. It's the 10uF cap in the passive input filter. Here's an electrolytic vs a COG. My fail and probably what those with the OSH Park board are seeing given I used its BOM as a design reference....

    That looks great! I find it interesting that you split the ground planes across the CS42448.

    Do you have your MCLK running straight from the Teensy to the codec or are you doing anything to...
