Soooo... I have Samsung HT-X715T 800w Home Cinema Speakers and dvd/amp.
The dvd/amps outputs are HDMI, Digital Optical, USB, and AUX(Jack). At the
Moment i have them connected to my PC Via Aux Cable(Jack to Jack). They
work fine BUT ONLY ON FRONT SPEAKERS AND SUB. I would like to know if
anyone has any suggestions on how to get sound through all of the speakers
instead of just the front ones. All the speakers definitely work because if I watch
a Film from the dvd/amp they all work fine. I am currently using Windows
XP and i have tried many times to change the speaker settings to home
cinema or 5.1 surround Sound but none of them seem to be working. ANY HELP??????
 
AUX cable will only give you stereo, as you already know. You will need to use the optical in on the Samsung. If your motherboard doesn't have optical, you will need to buy a sound card.

Using the PC, what are you intending to get 5.1 sound from, games?
 
Yes will you need a specific one, that's why I asked about games. You will need one with real time 5.1 encoding capability. Cheapest one is the Xonar DS, which has DTS Connect.
 
Bitstreaming PCM via HDMI is better than DTS or DD anyway, the only advantage a sound card has these days over a good external DAC is legacy game support, some old games have issues with modern audio limits in the OS from Vista onwards, modern sound cards try and work around this although they often fail unfortunately.
 
Yh i do but my dvd/amp doesnt actually have a HDMI function. its got USB, AUX, Digital and DVD, you can use a hdmi for the dvd but do you recon that will actually work??
 
Go for digital (optical preference, although optical is good too), and as long as your DVD has an audio stream for, and your amp supports, DTS or DD then you should be good to go.
 
A 7.1 card just has enough jacks for a 7.1 setup, but if you're using digital all you need is a single S/PDIF connection and some form of on-the-fly multi-channel encoding such as DTS or Dolby Digital.

hmm, do you think 5.1 coxial cable would work if i bought a sound card with coxial input ??

Not many sound cards use coaxial. You will pay more for a sound card that has coaxial, a Xonar D2/D2X for eg. That makes absolutely no sense really. Although, the D2/D2X supports both coaxial and optical. They are different cables used to carry the same information.

Won't the Xonar DG do 5.1 over optical?

Yes it will, however it can only pass on 5.1 audio tracks from DVD's and Blu-ray's etc. Music is stereo, and games produce 5.1 sound in real time. Audio needs to be converted into Dolby or DTS in order to be sent via SPDIF (optical/coaxial). The DG does not have that capability. If it did, it would have been more expensive, which would defeat the idea of it being a cheap great value card.
 
S/PDIF connections have limited bandwidth as they were only designed for stereo, in order to send 5.1 audio there needs to be some compression which is where DTS and DD come into it. Most DVDs are encoded with one or the other, and a lot of software can use the S/PDIF passthrough option which just sends the DTS/DD audio. In the case of games which are 5.1 PCM they need compressing and to do that you need a card which can compress audio to DTS/DD on the fly. Unfortunately as is the way these days, you need expensive licences to do that and thus Asus, Creative and other companies need to raise the price of their cards in order to offer us DTS encoding capabilities.
