I have a TCL Roku TV, 4 speakers, Soundbar Pro and Bass Bin. I can only connect the bass bin and 2 speakers. I cannot connect the sound bar pro or add the 2 rear speakers to get the surround sound. I bought these from Roku because they show that exact configuration. What am I missing? After I connected the bass and 2 front speakers, adding the 2 rear speakers would be a breeze. Not so. They are not seen by the TV setup sequence. Is it possible I need to set up the Soundbar Pro (Which is connected thru HDMI ARC) and then connect the 4 speakers and bass?
