I have no idea what is happening with the sound in my game, and I can't find any reference to anything quite like it.

I get a periodically cycling squish sound. It happens every couple of minutes. It started recently, but when I tried loading to an earlier save, it was still there. I ended up going back hours, much before the sound originally showed up, and it's still there, in every save file I load.

I have no idea how to get rid of it. I know of sound bugs related to charging/cycling weapons, but it isn't any of those (nor is is cycling quickly enough.)

This is driving me crazy, and I'll try anything to get rid of it.

I found a save the predates the issue. I had to go back several hours to a save before I dismissed Hancock/took Nick Valentine. The sound seems to be caused by having Nick as a companion and running, which causes it to cycle.
