Sonos largre system fails to play. error seems to be SOCO ZGT event fallback disabled

Hello. I have a large Sonos system with 27 zones.

Homeassistant is showing the following error when I try to hit play on any given zone

Error calling SonosMediaPlayerEntity.media_pause on media_player.1_2_bano_estudio: ‘GetZoneGroupState()’ call fails on large Sonos systems and event fallback is disabled

when I check the debug logs, I get the following

2023-03-07 19:50:07.369 DEBUG (SyncWorker_7) [soco.zonegroupstate] ZGT event fallback disabled (config.ZGT_EVENT_FALLBACK)

Searching around, the soco documentation states that the soco.config.ZGT_EVENT_FALLBACK= True* is the correct setting for large Sonos systems (see Here), but that option seems to be set at false in the Sonos homeassistant integration.

Is there anyway I can change that configuration value? If so, where would the change need to happen?

I’m trying to get the system to work, but it seems like it needs the fallback option enabled.

Has anyone found a way to fix this?

Thanks to all!
