Static and audio feedback through the Headphone jack on OLED LE

Got my OLED LE yesterday and I've noticed with IEMs that I'm getting this steady static noise/feedback sound from the new deck. Did not have this issue on my original deck, but I've seen a lot of older posts discussing this kind of issue on the original deck after searching. So....just a heads up, test your audio jack. I am probably just going to use a USB C audio adapter, NO way I'm going through the RMA process for this.
