Thk you for trying to help. Sincerely i don't what i did (i guess i did nothing) and last time i played it was a REAL 5.1 and it's so great to be able to localise all the sounds around!

Hi kklownboy, I hve a Xfi card to and can't make it work in 5.1 with Arma2. Did you do something special to make it work?

Here also it seems impossible to have a real 5.1 like in hundreds of other games. Creative X-Fi Xtreme Audio PCI-E With latest drivers and speaker set to 5.1 It's STEREO with ANALOG connexion and STEREO with DIGITAL connexion. No way...
