Don't know how your components are hooked up, but on most Samsung's including mine, you need an optical cable from tv back to receiver,as hdmi from tv to receiver WILL NOT produce 5.1 only stereo...try that and good luck
I recently purchased a Samsung LED LCD TV, the UN46B6000. I'm having issues with the sound through HDMI. When connected to a Blu-Ray/DVD player, the sound is very muted and the voices even more so. I think it may have something to do with the audio input to the tv switching to a 5.1 format.
When watching a blu-ray movie through my Sony PS3, I noticed that the previews before the movie sounded fine. When the actual movie started, however, I had to turn the sound up a lot to hear, and even then, the sound of the voices was very low. I am thinking the sound changed because the format changed from stereo to surround.
This is the same problem I had when watching from a different dvd player, so I assume the problem is with a setting I have on the television. The PS3 can output sound in various formats including bitstream, PCM 2ch, 5.1, and 7.1, dolby 5.1, dts, etc. The other hdmi input from my DVR sounds fine, presumably because it's in stereo.
Is there a setting on my tv I can set to receive and play the sound properly? What format should the sound be in for the tv?
