Beta - Windows

When using a Sound Blaster Audigy 2 series or X-Fi series sound card in a 64-bit Windows system with four gigabyte (4GB) RAM or more, various issues can be experienced. Often sound playback becomes jittery, choppy and noisy and recording fails to work. Sometimes you can record sound, but it's horribly noisy and scratchy. This happens with the latest 64-bit drivers for both product series, under Windows XP 64-bit, Vista 64-bit and Windows 7 RC1 64-bit and other 64-bit Windows operating systems. The issue goes away if the computer can see only 32-bit amounts of RAM, as in 4GB of address space minus PCI addressing. On a 64-bit system with 4GB of RAM installed, disabling Memory Hole Remapping in the BIOS makes the issue go away, since there is no RAM amount above the memory hole address space. Consequently, disabling Memory Hole Remapping on a 64-bit system with more than 4GB of RAM does not solve the issue, since there is RAM above the 32-bit limit of address space. Many users have reported varying issues most likely relating to this, such as noisy input and output, corrupted audio and a complete loss of EAX and ALchemy functionality under all 64-bit Windows operating systems. Consider this report a collected issue observation for 64-bit Windows systems with more than 4GB of RAM installed and usable. This is a serious issue, affecting all 64-bit Windows systems. It is severely hurting customer trust and the Sound Blaster brand.
