Hi I just install Radeon HD 2600 Pro For Windows Vista it has new Direct X 10. When I load up the video for first time nothing is wrong with it just the Audio. I can't here nothing I have Soundblaster X-FI with Front headphones connector and MIDI two ports also for other stuff. But I can't get any sound after I install Radeon HD. Do I really need to do something to able to work? I try load up BIOS on board audio is disable. The hardware seams to be working the Sound Meter next to the PC Clock seams getting sound single just fine but no sound threw headphones etc. Can you people help me out thanks! So I can enjoy my HD Card allot better then on Mute. Or do I have to get a soundcard upgrade to HD which I can do tomorrow on my day off. Its hard to keep up to date with new Tech Stuff. Then something else comes out better next year.
