Simultaneous Headphone and Speaker Support for Hearing Impaired

Thank you for your input.  I think we are facing the same challenge: having a hearing impaired person and a person with normal hearing listening to the same movie.  In my case, I want to use a sound bar (hdmi-arc) because the TV's speakers are not that good, and a blue tooth transmitter connected to the optical output of the TV but this seems to be technically impossible at this time.  I may have to resort to using the optical output exclusively, with an optical splitter to the sound bar and to the blue tooth transmitter but some people have complained about sound delay issues using this configuration.  Also I would lose Dolby Atmos (my sound bar is a Bose 600).  On the feasibility of using both outputs, I have also read some posts on another forum that reported that it was actually a CEC requirement that the HDMI-ARC and optical outputs be mutually exclusive (maybe to limit illegal copying).  If this is the case it would be up to the sound bar makers and the hearing aid makers to pressure the CEC for a solution.  If I am mistaken in my statements please do not hesitate to correct me.
