I upgraded my Windows 32 bit Vista computer to Windows 7 64bit several months ago. The only changes I made to the computer at the time was to upgrade the memory from 4 gigs to 8 gigs. I have a Creative SB X-Fi Fatal1ty sound card & an X-Fi I/O Drive in the
computer connected to 2 standard low cost speakers. This seup worked fine with 32 bit Vista.
I started getting the static sound from the start. If I rebooted the computer, the sound would be fine for a while & then the static would start again. I upgraded drivers, changed the memory settings, changed speakers to Bose Companion 2's & disabled everything
in the Creative Control Panel. None of that made any difference. I finally went back to using the on board sound card, but I really missed the front panel headphone jack & volume control.
This week I decided try to get the Creative card to work again. I updated all of the Creative software & drivers. I still had the static but not all of time after it once started. It would come & go. I decided to go to the Creative Control Panel & just start
changing settings to see if static would go away. If the static did not go away after changing a setting, I changed the setting back to its old setting before changing another setting. None of the changes helped.
Since I had 2.1 speakers I did not even consider changing the speaker setting from the 2/2.1. As a last ditch effort, I changed that setting to 5.1 & the static went away & the sound quality vastly improved. I then tried the 7.1 setting & the sound quality
got even better.
I have been playing audio through the Creative card for over an hour & a half, with not a hint of static & the best sound quality I have ever gotten on a computer.
I have also tried changing all settings in the Creative Control Panel with no return of the static.
I do not know why changing the speaker setting worked, but it did.
