ATI HD 6870 - hissing sound in 3D Tags: Radeon Games 3D Graphics Last response: May 6, 2012 7:25 PM in Graphics & Displays Share Yoan80 May 4, 2012 7:43:43 PM Wierd problem. When starting games i get a real bad hissing sound from the analog 3.5 mm jack on the onboard soundcard. Its a Asus p8z68-v pro/gen3 motherboard. Playing sounds when not in 3d games is fine. When changing grafic settings the hissing sound alters slightly. Using onboard graphics (removing the HD 6870) the sound is fine in 3d games. So that proves its the ATI cards fault. Any ideas? I have the latest drivers etc..

See if that eliminates it. Yoan80 May 5, 2012 7:13:50 AM Thanks, but already tried that.
