What I have done so far :- Updated Realtek Drivers to latest Tried all the different settings in AC3 Filter 1.46 - One at a time Tried SPDIFER (10/2007) with all the different setting DVD's running Dolby DIgital or DTS run perfectly with no sound quality issues. These are stored on DVD Disks or a Hard drive on the network What other things can I try to deduce where the fault lies. [/QUOTE]
