The issue: If you use a pair 300's as surrounds with your ARC in my case, you will not be able to use a second pair as a stereo/atmos pair in a different room with the new update. (worked before). You will start to get 'cannot connect' errors when selecting and deselecting speakers for whole house playback. You notice audio cutouts in the rears with your ARC and music. You may lose your subs even though they are connected in the app. No atmos in rooms with arc + 300 rears in one room and 300 pair in another room when both are selected.
I factory reset all my speakers, rebooted my firewall, modem and Access Point, Same problems,
I put the media room all on ethernet except of course the 300's, Same problems.
Level 1 Support
Sonos support level 1 tried but ultimally ssful ok'ed me to go to level 2
Level 2 Support:
I decided not to call and do more testing
My Testing:
I factory reset all my speakers, rebooted my firewall, modem and Access Point, Same problems,
I put the media room all on ethernet except of course the 300's, Same problems.
The fix:
I removed the 300's from being rears, added back my old sonos ones.
I moved the 300's to the front of the media room for music only in a stereo /atmos pair. (sound great, with no sub) created a new room just for them
So two pairs of 300's set in 2 pairs in 2 different rooms. 1 mini-sub in the living room.
Atmos now works on both 300 pairs and the arc simultaneously.
My System
ARC, 2 Subs Gen 3's and 2 ones as rears
four 300’s in two rooms as pairs.
RAY and 2 ones as rears
Move, Roam and Port
My Thoughts:
I don’t think their testing of how the software handles the situation of when a customer uses 300’s as rears with a soundbar and wants to use a second pair in another room was done as well as it should have been as the system was working correctly before the latest app update.
I wish they gave you a way to rollback an update, this way I could know for sure.
My hope:
With this post, is that support log it as an issue for inclusion in the next update.
My take:
The 300's are far superior to the ARC for music, you might be wasting them using them as rears.
