Hi guys I'm looking to get Simvibe setup but before I make the $89 purchase I'm trying to figure out if it will even work with my setup. Quick rundown of the setup: iMac late 2013 running Windows 8. The iMac has a 3.5mm out which is also an optical S/PDIF out for 5.1 (I have a 3.5mm to optical out cable, red light showing although its showing as 'headphones not plugged in' in the Sound in Control Panel). Creative X-fi USB Pro 5.1 (connects via USB to the iMac and outputs to a Logitech Z-680 5.1 surround speakers with RCA's) 1x Buttkicker Gamer 2 (might get 1 more later) Has anyone ever used Simvibe with an iMac. Any help would be greatly appreciated. Cheers.
