Audio crackles with multi GPU setup

Hey Unreal community!

I may have run into a bug in the current engine which has to do with multi GPU setups when you open windows on the secondary screen. Here’s my current setup:

I have 2 GPUs installed, a Nvidia 760 GTX and a 610 GT.
The 760 has 2 monitors attached, a full hd Samsung (1) and an older LG (2).
The 610 has 1 monitor attached which is a full hd (3) too.

The main UE4 editor window runs on (1), I have another one on (2) which shows me the world outliner. properties etc.
There’s a content browser window open on (3) which allows me to work more efficiently while having the game in nearly full screen on (1).

In one of the projects I am working on I’ve recently set up a sound cue which fires when the character makes a footstep. When this happens or when I play the sound in the editor, it is crackling a lot. However, if I close or minimize all the windows on (3) so UE4 Editor is only running on the 760, the crackling is gone.

Is this a known issue?

Below are some screenshots of my system specs. Please tell me which additional information you need to be able to reproduce the issue and I’ll do what I can to provide more details.
