Well, the video was made spontaneously and about 1 minute after Reticuli asked for a video. And this was the second try, cause i filmed it the wrong way the first time (also happened though). So quite a solid repro, i think.
I could try to redo it with mp3’s and WAV’s. I have those. But i currently am not able to and very busy, so lets see if you can reproduce it with AIFF’s at the office first. 
Also: i am on firmware 1.2.0. Firmware 1.2.2. is bugged for AIFF playback, as you can read (and is reproduced very solidly) in this thread: 1.2.2: electrical interference noise when loading new tracks
Not in the mood to upgrade to 1.2.2. again to test if that firmware still has the issue. It probably has, because all previous versions have it. Plus i’ll have to downgrade again, and am busy enough as it is.
