I just got my Asus Vulcan today. Am really impressed with the ANC, but I noticed a problem as soon as I connected it to my computer. Every time the computer does anything, be it receiving input from the mouse, or using the hard disk, then I get some digital white noise. The headset is plugged into the front audio ports, but I tried my speaker's headphone jack and still got the same noise (the speakers are connected to the back). Interestingly, I cannot hear the sound through my speakers, just when I plug the headset in. Full specs: Intel Core i7 930 Asus P6T SE XFX 5850 Black Samsung HDJ*random numbers* 1TB Antec True Power 650W On board sound USB Razer Deathadder I tried the back ports to see if the headphone wires trailing inside the case would pick up any interference. I assume I can't hear the noise through my speakers because of the different impedences/an amplifier. EDIT: Slight update, it seems as though the effect is most noticeable while in Firefox, but impossible to hear in a game or on the desktop. The plot thickens...
Try unplugging your USB devices and see if it goes away? Otherwise it might be time for a sound card.
Yes, at some point I do want a soundcard. But as the problem is mainly in Firefox, which has little to no need of a headset, I think I can live.
Try setting the power plan to high performance or otherwise disabling switching of the CPU to a low power state. When the CPU frequency is constantly changing, it can cause large current surges which lead to noise (or something like that), so this might work as a temporary solution.
hello sir, i have the same board and gpu and had the same problem, the sound of a grinding car gearbox through the speakers all the time/unsuppressed car stereo noise is similar, when i took my pc to bits to add second gpu, i also updated bios, fresh install of windows, fresh ati drivers, and the noise vanished, i dont know how it was cured but i did do my head in for months.
Well it seems to only be particularly noticeable when I am browsing the web, and even so, I can ignore it most of the time. I don't think I'm up to reinstalling drivers and messing around with settings - modding Skyrim for a few hours did my head in as it is. But thanks for the help all of you, I'm sure it will be useful stuff to know in the future.
