ADAU1452 – Ripple/distortion occurs at low signal levels when using the xover filter.
The signal is distorted, similar to the blue response curve, when the volume is low using the General (2nd-Order / Lookup) filter on the ADAU1452. With other filters, this issue does not occur. I also

Best MCLK source for an MCU-controlled HDMI DSP setup
I purchased an ADAU1452 Core Board from MediaWorks (aka MidiWorx on AliExpress). The board mounts an ADAU1452WBCPZ (#2201 D 5625508.1) and is very well designed, including pull-up/pull-down resistors
