H77 Pro4/MVP Optical SPDIF Crackling sound after installing realtek drivers

[asharkman]

Hey guys,


When I install the realtek driver all i get is a crackling.
I'm connecting to a DTT3500 through optical.
It works fine when i'm using windows drivers so i know the hardware is fine.

I've set the default format to be 16 bits, 44100hz which works when i'm using windows drivers in te realtek HD Audio manager but no luck.
I've tried re-installing realtek drivers but no luck.
Any ideas?

Cheers
Paul.
