Thank you for your answer. I wasn't aware of that. But still, I wonder how you can work around an HW interference by modifying SW, especially when sound is involved.
Do they apply "noise reduction" on the output to make the interference sound disappear ? If they do, they would have to detect whether the remote is plugged or not, so they don't change the sound when it shouldn't be. I'm not a sound programming expert, so maybe I'm talking nonsense here. And it would be a rather bad way to get rid of the problem I suppose (not to mention the noise generated by the interference might be different from one device to another, so using this technique would be unreliable).
Or maybe they have found what was causing the interference, and changed the way they're displaying stuff on the remote ? In that case, they're either really good, or really lucky that they could find another way to do things and work around this HW problem.
