Can someone direct me in the right direction. I just got some new speakers but I cannot get the sound working via optical.

I sussed out that it might be something to do with the SoundMAX drivers.

Reading some posts it appears that the SoundMAX drivers on ASUS own website are not the latest ones...

Where can I get the latest SoundMAX drivers from, for Windows 7 64 bit OS?

Many thanks to all replies in advance.
