I recently purchased the LG SJ9 soundbar which is set up for Dolby atmos. However, my TV (also LG) is several years old so does not have atmos support. Is there any way I can get atmos? I know that I can't utilize a receiver with the soundbar and was told that if I hooked up an atmos DVD player, I would have to use several different audio sources for different inputs. For example, I was told that I would have to connect the DVD player directly to the soundbar, then utilize an optic cable for the cable box since there is only one arc input on the soundbar. Is this correct? Why can't I hook up the DVD player to the TV, leave the connection to the soundbar as is, and have the DVD player process the surround mode? Why would the tv have to directly support this feature? Hopefully my question is clear.
