I used true play to set up my surround system. Now, if I go to the Sonos app>System>TV Speakers (+Sub+LS=RS)>Sound>Surround Sound> I see TV Level for each surround speaker which you can adjust the level of each from -0 to +15. If I change the sound level of the right speaker nothing changes. However; if I move the Left control it changes both speakers not only the left one. Do I have something out of wack?
