No Sound, Which drivers may i need?

I asked some questions yesterday and got a little response but i stil didnt manage get my sound working.

I installed win7 a couple of days ago on a new custom built pc but i cannot get sound.

In the bottom right it just says Digital Audio (S/PDIF) .. i have no speakers in my monitor so i bought some logitech ones, they are all plugged in right placees

Any help please? i cannot figue this out at all

A few questtions. Do you have the driver cd that came with the MB? If so it should have Vista drivers on it. Also need to know if you are running 32bit or 64 bit. On the Asus site I don't see the M4A78-STD It lists the M4A78-SE/95/Roem/SI, and the sound as Realtek Audio V6.01.5821 ASUSTeK Computer Inc.-Support- You should be able to install these in compatibility mode. http://www.sevenforums.com/tutorials/316-compatibility-mode.html Is the audio device listed in your device manager? Can you go device manager and click on sound devices and expand the view, then post a snip of it? http://www.sevenforums.com/general-...ed-method-uploading-posting-screen-shots.html This way we can try to force the install from update driver. Or you can try installing the latest Realtek HD driver from here http://www.sevenforums.com/sound-audio/3756-latest-realtek-hd-audio-driver-version.html Thanks I'll check back.
