Batman -Arkham Asylum, Audio Problem

I installed Arkham Asylum on my PC a few days back, at that time I only got audio during the cut scenes, but not in the game, later my windows updated all drivers, and the audio started working, but the game started lagging, I looked for fixes and one place they asked to uninstall the graphic card drivers, and reinstall them, i did it, it stopped lagging but then again, the in-game audio stopped working, any help would be appreciated


Specs:
Precessor: Core i5-2400
Mobo: Intel DH67BL
Ram: 4GB DDR3 1333MHz
GPU: Sapphire Radeon 6850 1GB

Thank you

There also appears to be a massive number of bios updates to it.

I didn't check that out at all, looks like I have a lot of downloading to do, i'll repost after finishing

and it worked, thanks a lot, silly Windows lol! i'm never gonna let it update my audio/video drivers again

Just to clarify you only need to most recent bios
you don't have to install them all.

hahaha yup, i know, i meant lots of downloads coz of the audio driver, Graphics driver, and then the BIOS

thanks again for that, i'll just install this latest BIOS update, n then won't look at it for a while :)
