I have a Roku Express (3900 series) and recently purchased a replacement remote, specifically the Enhanced voice remote, and the private listening feature does not work. When I plug in the headphones, it recognizes that they are plugged in, but no sound comes out. I checked the posts and completed all troubleshooting tips. I purchased this remote specifically for this feature. I may have to return. Anyone have any tips? Or know if this is a compatibility issue? All other features including voice work fine.
