Hi everyone!

I would like to ask a question regarding the setup of the SONOS arc + 2 eras 300 + sub. 
I have connected such system together with a Lg OLED EVO and it works great. However, I used to have a Panasonic system that had two standing boxes (now substituted with the eras 300). The difference between the older Panasonic system and this new SONOS system is that the voice of the people speaking on the TV can just be heard from the SONOS ARC in the front, instead of being heard from the eras 300 too. From the eras 300 I can just hear the music of the films, so the soundtrack. In the other system I use to hear everything from the stranding boxes I had.
So my question is wether it is possibile to change such thing in the way that the voice is hearable from each era 300 too.
Thank you
