Why wont the sound on my tv work?

Surround sound system wont work on TV but works on DVD?

• Hey.. my TV is about 3 months old Samsung - PS51D550 - 51" plasma 3D TV - 1080p (FullHD) and I've just brought a Panasonic SC-BTT270 5.1 3D Blu-ray Home Cinema System.. basically it works fine when watching a DVD but i cant get it to play sound when watching TV.. the back of the TV has 4 IN hdmi ports but no out ones.. i have tried using a hdmi cable for sound an AUX cable for sound and an optical wire for sound and all at the same time and none work! any help would be much appreciated.

  This is an issue i have been having for quite a while now and i have done a lot of research as to why i can't output surround sound while watching tv but i can while i'm watching a dvd or have a ps3 plugged in. I too have a Samsung 32" LED TV and a Samsung surround sound system and so far i have found that only the two front speakers output sound while watching tv. I have an HDMI plugged from the surround sound into the TV and also a optical (toslink) cable. I have found using different modes on the surround sound doesn't make a difference apart from one mode called Matrix mode but this only shares the sound across the speakers resulting in a flat and a below par sound so i just use stereo mode which is crisper even though its just from the front two speakers. I have tried all different connections like you have and i can't get them to output to every speaker and sound good so i resulted in plugging extra speakers into the ones that work at the front and spreading them around the room (plugging wires into the back and splitting the sound) some say this is a bad idea but it seems to be alright so far. I have read though if you have Sky+ HD (the new black box) which i have in my front room (surround is in my bedroom don't ask why) that the Sky box has an optical port which you can plug a toslink into a surround sound unit. One thing that has to be remembered is that most programs on television aren't made or filmed in Dolby Digital Surround Sound so even if you have all the necessary equipment you won't hear it from all the speakers unlike films and playstation/xbox games which are! From the sky guide you can see by pressing info which programs have surround sound by the two letters DD in the top right hand corner of the info box! I hope this helps with any uncertainties because it can be quite a complex issue and one that isn't explained well by manufactures of TV's or Surround Sounds!
