I suggest using one of the interfaces based on the C-Media sound chips. There is only one cable to connect to your computer, PTT is handled by a GPIO pin on the sound chip and your system sounds will play through the PC speakers, and not be transmitted. This page has a list of compatible devices and instructions to build your own:?
