Sound when running a dual screen setup

I like to play Football Manager and have it running on my right hand monitor and on the left one I use Firefox and whatever else Im faffing around with. Now my question is, when Im playing FM and I have a match playing I can only hear the match sounds when the window it is playing in is the selected one. If I click elsewhere, say on the start menu or on a webpage in Firefox the sound stops as FM is no longer the selected window. Im pretty sure that previous versions of Windows didnt do this, is there a way to force the sound to continue to play?

I am currently on my laptop and loaded up the previous version of Football Manager and it does the same thing when alt+tabbing, all sound cuts out as soon as the game isnt the active window. When you think about it its something that you would normally want to happen (the sound cutting out) when you alt+tab out of a game briefly so I can understand why it happens (if its something that is supposed to happen through Windows programming).

To answer your questions, I have messed around with which monitor the game is displayed on and it makes no difference and I have only recently done the drivers as part of a clean install.

Will give it a go tomorrow when Im downstairs. Sat in bed and its too cold out of it so there is no way Im getting out just to try it
I have it as extended, doesnt duplicate just make the 2nd screen an exact copy of the first?

Thats what has me confused.
The only other hits I get when I google this is to do with WoW and the person asking about it is promptly told there is a play in background option in the settings. Unfortunately there isnt in FM. Have even asked on the developers site and not had a response from anyone

Still not figured this out

*Bump*

Anyone?
