FireTV or Receiver Audio Buffering Issue

I've been having an issue with my audio randomly getting distorted primarily when watching netflix on my FireTv. The best way I can describe it is a robotic two tone rhythm that cuts in and out with normal audio. I don't think this is strictly a buffering issue since I think I've heard it when I was on the menu screen, but the sound is rarely constant on the menu screen so its hard to tell. I have the FireTv going directly into the TV then sending the audio to my receiver using the HDMI ARC. Anyone had any similar issues?

Thanks in advance!
