Phaseflare even kills the audio!

By the time I’m finished clearing an area with my phaseflare, there is a static sound that will never go away. It causes all of the other sounds to become slow motion and choppy. It won’t stop until I quit and reload. It’s like a fps drop rate, but it’s the sound not the video. Anyone else? Could it be something on my end? I’m old, technology impaired, and confused.
