i get the buzzing from scrolling on websites, moving the mouse, and basically doing anything on screen. the noise gets extremely intense when i load up a game and get a high framerate.
1) problem was present on old motherboard/cpu/power supply/memory/hard drive (rules them out)
2) problem still present on brand new RMA'd xonar essence ST
3) problem persists, but is not as loud when the soundcard is disabled in device manager (i hear it click off)
4) problem is NOT present when using onboard audio
basically everything in this system has changed except the videocard. i am having a hard time blaming the videocard because the problem is not reproducible when i use onboard audio.
also, the problem is not present when the computer is posting and halfway into windows loading. it only begins about half a second before i hear the soundcard physically "click" on while windows is loading the audio drivers during boot. i thought it may have been a audio driver issue, but i have the same problem in safe mode. perhaps it is another driver that loads with windows?
i have reset the bios to default settings, disabled pci clock spread spectrum (if that has anything to do with it), and reset my video cards voltage and clock settings to default. NOTHING helps.
i have tried different RCA cables which did not help either.
I have the latest chipset drivers for my motherboard.
