Are you connecting the TV to an amplifier, or just the ceiling speakers?
I am trying to connect my TV to a sonos box which is basically allowing the sound from my TV to run through my ceiling speakers etc. Reading the manual i simply connect a twin audio into the provided jack which plugs into the AV(VIDEO)/(L-AUDIO-R)socket on the back of the TV and then switch on the external speakers from the remote. I am not getting any sound from the external speakers - can anybody advise me on what i may be doing wrong!!!!!!
