I need the same feature. We have a family member who's hard of hearing and needs earphones to watch TV. But others want to watch at the same time. I purchased a Roku Streambar with the add on speakers (2 side, 1 base), but it appears this can't be done. If I can't get it to work, I'll have to return everything and look for another option. It's sad that with a Roku hearing impaired people can't watch TV with anyone else, they have to watch alone (insert sad face here).
