Is it possible to add a sonos beam as a center speaker which is connected to your amp that has other (non sonos) speakers connected to it? Assuming i could connect the beam to an HDMI input on receiver and assign that input within reciever to output with the rest of the speakers. TV is connected to amp through an optical cord. OR is it better to connect the beam straight to the tv? But not sure I can then play through the center and the rest of the system if TV sdoesnt allow two different sound outputs
