Hello,

There is something happening after reproduction of high sample rate audio (352, 384 KHz, maybe DSD).
I've captured this with Maudio Transit and this is the link to wave file.
Config is Buffalo with IVY III, Amanero with Acko syncronous reclocking. Arduino UNO for i2c control and display.
It's standard windows test audio from Digital audio properties. Noise appears after playback and remains until lower sample rates are played.
I probed clock and data lines with scope and everything is OK - no data on sdata and clocks are fine too.
