Three way 3.5" audio splitter

[Trapper]

I need help, and my brain is frazzled trying to figure this out.

 

I've got one set of speakers which connect to via the standard 3.5" jack.

 

At the moment it either connects to my PC via soundcard or my monitor for my Virgin HD box in the office (using HDMI from the V HD box to my monitor and then plugging the speakers into the monitors 3.5" jack as it doesn't have internal speakers).

 

It's a bit of pain to keep swapping the cable over so I'm looking for a splitter.

 

Effective it needs three female 3.5" jacks one output (speakers) and two input (PC and HDMI)

 

Anyone know if this exists?!

Bah done it.

 

I never knew Windows Vista onwards allows you to play microphone input straight through the speakers.

 

Last time I tried this was on Windows 2000 way back when and you couldn't do it.

 

Nice feature!
