I have just got a Dell Inspiron 530 desktop. I have some Boston speakers from my old system which consist of a subwoofer and two speakers. The Subwoofer is powered and the speakers are connected to it. There is one green jack plug from the speakers which connects to the PC.

 

My new Inspiron Desktop has an integrated soundcard HDA 7.1  I cannot see that there is a port on the back of the PC to connect the speaker jack to.

The headphones work perfectly well from the headphone jack on the front of the PC but I just do not know how to connect the speakers.

 

Can anyone help.

 

Thanks
