I have two questions about headphone use for the new Roku Soundbar:
1. Can you play sound over the soundbar and the headphone jack on the remote simultaneously? I have a family member who is hard of hearing and needs to be able to use headphones without affecting everyone else's ability to hear.
2. Do the headphones work for any audio playing through the soundbar (i.e. for what is being watched on cable or a blu-ray player), or only for content being played through Roku apps?
