Did you check the ribbon cable from the mainboard to the IO board in the DCX? This ribbon cable carries the audio signals with some DC voltage: they are known to have bad connectors. (Connection between cable and connector is bad.) It starts with noise/his and eventually drop outs on channels. I have 3 of these units, all with the same problem. I soldered the ribbon cable to the IO board and replaced the connector on the cable at the main board side. No issues since then...
