I still have this problem, but only on tracks recording AUX IN 1-6/T sources on my X32 Rack Console. Firmware on both devices (console & expansion card) is the latest version (X32 3.09 / uTrack 5000). I loaded a recorded file into my WAV editor and had a look at the signal. Partially the signals have been cut on the bottom all on the same level. This is what obviously the noise comes from. Once again: It only appears on recorded AUX IN 1-6/T channels! Recording AUX OUTs or XLR INs works well. Are there any workarounds?
