After I close remote desktop go back on my computer to use teamspeak the sound nor microphone works, I have to reset it with selecting one that doesn't work at all. Than put it back to the one that does to get my sound plus microphone to work. I'm not sure if anyone else has a issue like this but I ensure you this happens.

O/S - Windows 7 Professional. x64
Sound card - Realtek HD audio.
Headset - Plantronics usb controlled.
