Recently bought 3 sets dsp 500's to use on our network at home. Downloaded their software and get audio but no voice. Support from Plantronics say its an application problem, the mics work when doing the test. We are trying to use them in Battlefront so i contacted lucas arts and they said its not a game problem but set sound card as primary in audio control. That caused them to not work period. Any body out there have the same or similar problem? I would appreciate any help, my kids would love to rub it in after they blow me off a platform with a missile launcher! Thanks
