Can be many reasons like having HDMI 1.1 in combination with HD sound won't work, if your TV cannot handle audio over HDMI, if you have a received check receiver specifications... check the files, which codecs they use....

ETC...

that TV does support audio over HDMI. but NOT ac3 or DTS just bitstream pcm the tv decode. other formats you need external decoder
