PC Audio Discrete 5.1?

[jerkinjohn]

I have my optical Toslink hooked up to my theater system and it sounds really good but it doesn't seem to be Discrete 5.1 surround like my 360 produces. In my game settings and PC settings it says it's 5.1 but on my reciever it does not show thats it's getting a discrete 5.1 signal. Any thoughts on this?


Edit: Opps sorry guy's I just got my answer!

im just saying, that an optical/coaxial connection by itself, will not deliver 2 channel PCM as a surround signal, 2 channels isnt surround (obviously)... but, that is all you can get via a 2 channel signal

without dolby digital or dts encoding (and some other surround formats im sure)... there is no way to get discrete surround sound over a digital connection

on the receiving end however, the digital decoder can decode that pcm signal as a 2 channel source, and upmix those 2 channels into simulated surround... but, you still only have 2 discrete channels regardless

In addition to that quote, your system have to be Dolby Digital Live (DDL) capable.
