A friend of mine has just installed his Sonos system (2x PLAY 3 and 1x CONNECT - wifi connected, no BRIDGE or BOOST). The CONNECT is optically connected to the LG soundbar. When playing all devices in group mode, the output from the soundbar seems slightly out of sync from the PLAY3's. This is very annoying and spoils the whole experience.
We have run basic diagnostic stuff (e.g. looking for interference, channel selection, analogue vs. optical connection, reset of all devices, etc.). Wifi strength is great in all rooms (2x electrical system boosters in place).
I believe it is a communication issue between the CONNECT and the LG soundbar, but can not find any data in support or forum. Can anyone provide any information or better still guidance?
He plans to raise a call to Sonos support and submit a diagnostic.
