I just recived Tactic 3D Sigma, I'm going to use it in multiplayer games, Skype, Team Spek etc. Unfortunatelly it's USB sound card is not recognised correctly by my computer. After installing drivers and restart, I have no sound, Creative control panel isn't starting, because he could not find compatibile device. In Control Panel/Sound I can't find any device, and in Devices and Printers ther is Tactic 3D Sigma, but it's unrecognised device... I think the problem is from this, that I have Audiotrak Prodigy HD2 PCI sound card installed in the same time, in my rig. But I'm not going to uninstall it - I'm still using it, for listening music from speakers. I need installed this USB card to use earphones and microphone at tha same time. Don't know what to do, help Main components of my rig: Intel Core i5 Ivy Bridge, MSI mainboard (standard sound card drivers not installed); Windows 7 64 Home Sorry for my language.
