Windows 7 audio problem on WINDOWS 7

[shy12]

i have a problem...i have the last version of Win 7 x64 and everything works perfact like vista but i have one problem with the sound....i have "IDT high definition audio codec" installed on my computer and i connected it to a reciver 5.1 with a optical cable....my problem is when i play a movie on the computer its doesnt work on all the speakers like its supposed to.
u know... the sound supposed to be splitting in a diffrent way to each speaker. only FL and FR works.
on vista its was working perfact.
for those who wondering...i have installed everything (codacs for 64 bit and for 32 bit)
what i need to do?

If you go into the configuration for the sound(Right click on the speaker in the tray and select playback devices, and then select the one you use, and hit configure) you should be able to change it to 5.1 surround.

Another way is to open the control panel, click 'Hardware and Sound' and then just 'Sound'. You'll then see the sound properties box, highlight the speaker and click configure. (see attached screenshot)
