No sound through sub when connected to PC

[David Short]

Today i bought a Philips 2.1 dynamic sound SPA4355/12 system for my PC.

Getting not to bad sound out of it, The only problem i'm having with it is i am getting no sound out of the sub. I do get some feed back from the sub when i plug it in, so i'm hoping its still working.

Any help would be appreciated. if you need any more information just ask

Not to sure where i should be posting this. if i have put this in the wrong place just tell me and i will get rid of it.

Hi
How does that connect to your PC,One or two plugs ?
How have you got your speakers configured on your PC ?

It just has a single 3.5 connector. And its set up as 5.1 surround

Right that is why the sub is not working as the PC is filtering it out first,your sound system needs a full range signal and it then filters the sub signal itself,you need to set your PC to stereo two speaker.
