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.
Before you do that, try other headphones with your Steam Deck. Based on the comments here, I think the problem is mostly with IEM’s, and maybe this commenter is using headphones?
