Crackling Noise On Recording Track

I don’t know if this is related, but my recordings have a terrible noise to them on all tracks.

Last Sunday I recorded about 3 hours with no troubles.

Friday night I recorded a good 5 hours with no troubles whatsoever.

Saturday and Sunday I recorded about 10 hours each. All 32 tracks of every recording sound like this:

The only thing I can think of is that I’d loaded last Sunday’s snapshot on Saturday. Everything else is the same – same power, same hard drive, same control network. The equipment was packed up and moved each night, so the equipment was hard booted each morning.

The card, the X32 Rack, and the SD16 are all at the latest firmware, and I was triggering recordings via the app. The live sound was pristine, and the board was running at 48KHz.

Now that I’m home with the equipment, I’m unable to reproduce the problem at either 48 or 44.1, and the tracks recorded are perfectly clean.

Is this a facet of the same issue, or something different?
