how do i split a surround group arc+2era+2xsun3 to use 2 x era 1x 300 and a sub3 as its own group
i have many sonos speakers in my home, in the living room i have a arc + 2x era300 + 2x sub(gen3).
i would like to create a group for the era 300s and one of the subs for music only without effecting the use of the sourround set when driving from arc earc tv setup. in other words i would like to occasionally just use era 300s and a sub when listen to music only.
