Could you give us more details please?
What exactly do you have connected via the DVI & HDMI cable?
What's your sound card, or is it integrated sound?
What speakers are being used?
The more info the better, preferably separated by a line or some punctuation.
Is it related to your two posts yesterday click here & click here?
And can I suggest, before you simply tick a thread as resolved, to post some feedback about what you did & what worked. We're not looking for it, but a simple 'thanks' wouldn't go amiss either ;-), G
