Thanks, ***** ***** the blueray box. The tv model is
with Freeview and wi-fi built in. It as a 2014 build
The problem is now solved (15:52 Thursday). Your comments triggered off the thought that I had not checked the sound set up on the old box. The hdmi was set to Dolby Digital instead of Normal - I'm sure that was somehow changed when the engineer swapped over the old box to my second location when installing a new 2Tb box in my first location. The new box is set to Normal. Thanks help, it certainly put my thinking straight.
