help will be very much appreciated

When you start asking these sorts of questions you know it's time to invest in a AV receiver and home theatre system! Ideally you need a AV receiver in which the PS3 can connect to via HDMI and the PC would access the receiver via SPDIF. No unnecessary cables no mess. Without a receiver you can not decode the 5.1/7.1 Dolby or DTS bit streams from the pre-encoded PS3 games, hence why you get stereo only

Edit:

For Dolby True HD and DTS Masters you need a specialist receiver.

but is it possible to get sound through all 7 speakers with my current system weather its true surrond sound or not?

Most probably not, because whenever the soundcard outputs the streams from the PS3 it will be in stereo only regardless. You'll need a AV receiver capable of 7.1, HDMI output, fibre/coaxial output with the following codecs: Prologic, Dolby Digital, Dolby True HD, DTS Masters etc.

Edit 3:

The PS3 uses only 5.1 Dolby for games and 7.1 Dolby True HD for BluRay movies.
