Setup: Arc Ultra + 1 Sub 4 + 1 Era 300 + LG G4 TV (using eARC HDMI).
Goal: Connect everything to the TV in one Sonos room with synced volume, without relying on my phone for adjustments while watching TV.
Issues Encountered:
- After setup, I end up with two rooms: Family Room and Family Room 2. These can be grouped via the Sonos app, but:
-
Grouping requires the Sonos app every time I watch TV.
-
TV volume doesn’t sync properly with the Era 300 when grouped—its volume needs to be adjusted separately via my phone.
-
The Era 300’s output is slightly out of sync with the Arc audio
Question:
How can I configure my setup so all devices are in one Sonos room with synced volume, eliminating the need for manual grouping or phone adjustments?
