I need some help, I recently brought a plantronics headset 510, and it works fine, except that the sound comes out the wrong way. For instance, while I am playing a game, I hear things on the left, but it is really to the right, and the right is to left. I am using an intergrated sound card. This headphone has a soundcard of its own (built in), and there were no CDs or anything that came with them. I have uninstalled my intergrated sound drivers, but nothing changes, I have searched all over the net for answers. But all I have found were speaker topics, and how the solution was the cut the wires and solder them the correct way. But this is not the case with my headphones, it is one solid wire running from the USB to the headphones soundcard, and then to the headphones itself through the left ear. There is no wire for the right. Thank you for all your help.
