No Sound

[Twogoats]

I have a New old stock DVD Home Theatre System DAV-DZ210D which is connected to a Sony  KDL-37EX403 TV 

It's all connected and the Sound is Brilliant !

Before I got the Home Theatre System I had connected a PS3 which worked fine but now I have no sound with it ,it has a picture which is great but no sound .

I also tried connecting an Amazon Firestick and it's the same Great picture but no sound .

The TV has 2 Scart sockets and 4 HDMI sockets and a socket for a PC connection .

Is there an adaptor I can use to get Sound on Everything as it's really infuriating !!

Thanks

Whit that HT you have only get Audio from a DVD sourse, no way to listening Audio from TV or devices connected ti TV's...

The DAV has only OUTput and no INput...
