Bravia Tv / Blu Ray sound issues.

[Roguefarmer]

Hi there,

briefly, we have a Sony BDV-E370 Blu Ray player linked into our Sony Bravia tv by HDMI.

We also have a Sony HDD (SVR-HDT5008) attached into the TV via HDMI.

All systems are go and have been for a while but within the last few weeks I've found that whilst everything still functions as it should I can't seem to play the TV through the Blu Ray anymore.  Blu Ray films are still playable when I select the correct input but although when watching the TV via the HDD, the Blu Ray displays TV but doesn't allow the sound to come through.

All HDMI's Control options are on.  Optical audio is set to auto etc.  Cables are all checked.

What am I missing?  Is it anything to do with the Home Theatre function?

Cheers...

Alan
