Dolby surround sound for my headset?
I have a Plantronics Gamecom 780 headset that I used to use on my Windows, but since I prefer my Mac, I would like to know if there is any way to output 7.1 or at least 5.1 audio to the headset, since the software that came with it does not work on Mac. I've already tried Google but did't find anything, just a software called "SteelSeries Engine 3", but that only works for the SteelSeries headphones.
These are my specs:
iMac, OS X Yosemite (10.10), Mid 2011 - 27 Inch
