The head set has connectors directly into the desktop computer
I have tried inserting a USB connector into the desk top the inserting the headphone connecters in the the USB microphone / headphone sockets and that did not work.
The speakers can not be be configured here is the message
"We are sorry but we could not rconfigure your speakers . Although you will not be able to use Zoiper for audio calls you will still be able to talk to your contacts by using the chat function"
