Audio sporadically doubling/tripling up on S5

I'm experiencing an audio issue on the S5 where the audio of a playing song sporadically doubles up for a second or two. When I say doubles up, it seems like it takes a little clip of the song, say 2 seconds long, and plays it over the already playing audio a couple times. Although it's a bug, for purposes of describing the issue you can imagine that it sounds like a delay effect where the delay is running at full volume - getting 100% wet and 100% dry at the same time.

This happens without touching anything, and it goes away quickly. It continues to happen as long as I'm playing audio, as frequently as every 20 seconds.

I hear the audio doubling up in my booth monitors and in my cue headphones (which is terrible - you can't really use the headphones when you're about to be randomly audio-bombed). I haven't yet tested whether it comes through the master outs (for the moment I'm just playing in my room using booth outs, and recording/broadcasting TP3 from my mac, so not using any master outs).

Strangely, the effect is NOT captured when I record Traktor via the record button in the software. Maybe that means it's a hardware issue??

I've recorded a video from my phone showing the bug:


I have tried restarting Traktor, restarting my computer, even reinstalling TP3. Other potential factors: I am running Loopback in the background, and I am running the Supreme mod. I don't think these are the issue but just want to cover the bases.

I'm running MacOS Catalina 10.15.3, Traktor 3.3.0108, and the most up to date version of the S5 firmware.

Thanks in advance for the help!

 

Update, this may not be a traktor issue after all. I played a set last night using a Pioneer DDJ-1000 and Rekordbox, and the issue started to occur about 45 minutes into the set. Now thinking it may be a computer power issue. Would be interested to hear if other people have encountered similar issues and if you were able to identify the root cause.
