You are correct. This is from the Samsung UE40D6530 manual, which I had handy.

When the TV is receiving a DTV signal, the TV will send 5.1 CH sound to the home theatre receiver.
When the source is a digital component such as a DVD / Blu-ray player / cable box / STB (Set-Top-
Box) satellite receiver and is connected to the TV via HDMI, only 2 CH audio will be heard from the
home theatre receiver. If you want to hear 5.1 CH audio, connect the digital audio out jack from your
DVD / Blu-ray player / cable box / STB satellite receiver directly to an amplifier or home theatre.

A quick Google suggests this behaviour is very common.

I have a Panasonic G20 plasma which won't pass through Dolby Digital from the STB over HDMI to the home theatre system over HDMI or optical, necessitating a direct optical connection from the STB to the home theatre system.
