When watching regular TV in surround sound mode, the audio signal needs to go from the TV to the DVD/surround system. Like herks pic, you will need the red+white RCA cable from the audio "out" on the TV, to the red+white audio "in" on the back of the DVD player.
Like herk also said if you only have Digital Audio "out" on your TV you will need a converter. I would be surprised if that were the case...
I was ahead of myself:"ARC and HEC
HDMI 1.4 introduces two features called ARC (Audio Return Channel) and HEC (HDMI Ethernet Channel).
These features use two pins from the connector: a previously unused pin and the hot plug detect pin.
ARC is an audio link meant to replace other cables between the TV and the A/V receiver or speaker system.
This direction is used when the TV is the one that generates or receives the video stream instead of the other equipment.
A typical case is the reception of ATSC
signals by a TV, but reproduction of audio is handled by the other equipment.
Without ARC, the audio output from the TV needs to be routed by another cable, typically TOS-Link or coax, into the speaker system.
HEC provides a bidirectional Ethernet communication at 100 Mbit/s.
It also goes by the name HEAC (HDMI, Ethernet, Audio, Control).
