No.You'll need to use HDMI or optical/coaxial, and need to have a 5.1 speaker system.
For anything via AUX or stereo jack or SCART, these are all analogue stereo signals, and so they won't automatically decode by Dolby Digital or DTS.
What's used instead is Dolby ProLogic (DPL for short), or Dolby ProLogic II (DPLII) in either Movie / Music / Game mode. This is a later version of DPL which has better rear effects processing.
If these are not available then there's probably some in-house surround algorithm. Check the manual.
Typically, once set then the surround system will apply the same format of decoding to that input until the mode is changed to a different version.

Optical.is a good shout. So.long as the TV is set to pass Dolby Digital then your surround kit should recognise the DD5.1 signal for the HD channels that are playing a TV program or film that has a DD5.1 sound track.
The catch here is that not all HD programs have DD5.1 audio, and also the non-HD channels don't have it either.
In both these cases the optical lead will carry a stereo or a stereo+Dolby Surround (DPL/DPLII decodable) signal. So just having optical doesn't guarantee you won't have to set the surround system to DPL/DPLII or the manufacturer's in-house version of surround decoding.
