Im having this issue with an Auzentech Bravura 7.1 PCI Express sound card and my hifi system. I have a 5.1 hifi system with receiver set up on my pc with a fibre optic cable connecting the two.
The issues im receiving is when watching any form of video on the computer through any program, there is a 'lag' issue where on the video you see people speaking, but then 0.5 to 1 second later is when they actually speak.
So far i have tested different sound effects on the receiver, like movie/game/bass/rock/jazz all the different standard EQ settings but with no effect. I have tried using the latest drivers from Auzentech's website, drivers from the cd the card came with and previous drivers from the Auzentech's website. None of these give me any change.
Any tips/pointers/things to look for would be much appreciated.
