HDMi and Exernal audio at same time?

[gbu]

I have just hooked my TV up to my PC with a HDMI cable.
I have external speakers on my PC through the 3.5mm jack

Now i can get either select audio source from HDMI or the Speakers, but i want to play through both at same time if possible as my Pc is behind where i sit directly opposite the TV so im hoping to get a cheap version of surround sound if i can play both at same time

Ive downloaded AudioSwitch which helps me quickly flick between the 2 sources but i would like the option to at try to play through both, is this possible?

Many thanks

The Windows default (limitation) is only one audio playback device. There are some third party programs that claim they bypass the Windows restriction. I don't know what the programs are or if they really work. But, do a google search.
