Hello

We have a Sony BRAVIA LCD Digital Colour TV - model no. KDL-40EX713 and a Sony Blu-ray Disc/DVD Home Theatre System - model no. BDV-E870/E370 (but Sony speakers are not present as we use Sonos).  Whilst we have had these products for a number of years they are both still in excellent working order.

Our problem is linking our Sonos surround sound system (comprising of a subwoofer, Playbase and 2x Play:1s) and also connecting our recently purchased Freesat 4K recordable box.

When watching television the systems seems to only want to 'talk to' the Sony home theatre system and, as such, sound is not present via our Sonos surround sound system and plays only from the Sony TV speakers.  Similarly, when watching a programme on Freesat, the sound plays once again via the Sony TV speakers only.  We have also tried to play a DVD in the Blu-ray player - once again, what used to be great surround sound is now only played through the TV speakers.

However, when streaming music (from Amazon Music via our Sonos system) sounds is present on the Sonos surround sound system.

Basically, we think we have a set-up problem and would like some advice as to how we should be connecting our Sony BRAVIA TV and Sony Theatre System to our Sonos system and Freesat 4K box.  Not sure how the HDMIs should be connected - and where is best to connect the optical cable?

Any help would be greatly appreciated as listening to most things only via the TV speakers is somewhat frustrating!

Many thanks.
