How do I hear all the channels from my TV using my Home Theatre System?

Question

I just bought a Samsung home theater system. Everything is all connected and I hear my movies perfectly. I wanted to be able to hear my cable channels the same way so I went out and bought a optical cable, but unfortunately I can't hear all the channels. Only some of the channels I am able to hear and on some the voice goes in and out and on my theater system it flashes the letters LPCM. I thought it might be a problem with my cable box but my cable company came and nothing. Does anyone know how to fix this problem?

Answer 1

Your cable box or TV is probably not compatible LPCM oversampling above 48khz. Your Samsung will have a "downsampling on" switch somewhere in the menu, that will drop down to regular PCM. This should make things work fine. Check the Samsung owners manual for the location of the downsampling on switch.
