Hi,
I’m struggling with this problem from over a year and hope I can get it resolved.
This is my setup:
5 sonos Play:1 speakers in different rooms
2 sones Play:1 speakers in surround mode
1 Playbar in surround mode with the two Play:1 above
1 Boost
The Boost is hardwired to the Network and I am using SonosNet on Channel 11. All the other speakers are wireless.
Previously, I didn’t have a boost but I hoped the purchasing a Boost would solve the issue. I have reconfigured the whole setup from scratch. Uninstalled and removed all the apps from my iPhone and iPads, unlinked the accounts and reconnected everything.
What is the problem? All the speakers are visible and working correctly in the Sonos S2 app.
However, after a while, the Sonos speakers are disappearing from the Spotify app. Up until the situation that all speakers are gone and I’m no longer able to play music from Spotify on my Sonos system.
For now, the only resolution is to power cycle all the speakers, reboot the network and after a while they normally appear. However, within an number of days, they start disappearing again. The problem is that the speakers are fixed on the wall with continues power, so I basically need to shutdown the power in the whole house to resolve this temporaly.
