Thanks again for quick response, yep audio from new sound bar is fine when using other source,
the probs of crappy picture & sound bar dropping out seems to occur only with connection using the 3.5mm to 3.5mm cable - not sure why that is , but it is what it is.
So sounds like your suggested extractor/adaptor will be the go
Just so I understand, I assume the suggested box retains the digital signal all the way thru, thus overcoming the need to go from optical to rca anaoluge, then back from analogue to hdmi, which is what one of the local electronic outlets was trying to explain I would need to do.
Any, thanks again for you response, all makes sense, will let you know outcome when I get the box.
Great forum site, thanks, jacketts
