P5E optical out sound problems?

[mk_ln]

Hi,

I recently upgraded to the P5E and noticed that I can only get stereo sound (2 channel). I am able to get full 5.1 using the analog connections from the SupremeFX II card, but the optical doesn't seem to be working properly.

I have searched for quite a while and have found nothing that has helped.

Would anyone happen to know the cause and solution?

Thanks in advance.

What bios are you running? I have a P5E as well as the optical out gives me 5.1 no problems
