Loud static when playing videos



I have been browsing the forum for about a week now and still have not figured out the source of my problem. The problem does not transfer to playing videos from my PS4, XboxOne, phone, or computer. I have put my chromecast on a dedicated 2.4ghz wifi connection. Lowering the quality of videos from maximum solves the issue, but I would like to watch my videos in a greater quality than 480p. Followed steps from this forum post to no avail. Looking through the logs for 'speed =>' produced no results.
