Volume Slider Randonly Jumps to Zero

This is odd. While auditioning sounds in Finder Selection view, the volume slider in AudioFinder randomly jumps from wherever I’ve set it, to its lowest setting.
I’ll be listening to the sound file, then BLAM! It’s silent; because the volume slider has jumped to its lowest setting. I have to continuously drag it back to the desired level.
It’s as if it’s receiving MIDI control data and changing its position, but is that even possible?
It’s very frustrating and definitely impedes smooth workflow. Is there a setting I’m missing or a way to prevent this from happening?
