I just bought a Targa Visionary with the AMD Athlon 2200+ with "AC97 3D Sound". My question is:
I don't really understand the technical aspects of it, but I am under the impression that AC97 means that surround sound is coded into a single stereo-style output. According to:
How can I get Dolby 5.1 out of the single headphone style jack? Do my speakers need to have a special decoder built in to support?
I have a set of Dolby 5.1 compatible speakers that have signal inputs for subwoofer, front, rear, and center channels... But that would need 4 plugs while my laptop only has one..
Is there an additional piece of hardware required to decode this to Dolby?
