sonos hometheater

I have a sony smart tv a sonos beam 2 Sonos one 2 sonos one sl. Setup hdmi arc on beam 2 sone one sl as sorround and the 2 sonos one as stereo pair. Now when i grup them to sound all together on tv it sound with echos and every time i turn on the tv and put it on group also use apple tv and both the sony tv and apple tv remotes don’t setup as it supposed to be when i go to the settings and press vol up it dont find it. Main concern is the beam and the sl aourround grouped with the ones as stereo pair makes echo like 10 tvs are playing the same sound and the issue of having to turn on the group ever time i turn on the tv and the volume of the beam and the stereo pair are not even when up or down one is higher
