Thanks, but I guess I should have been more specific: can someone please verify that a particular sound device (such as an Audigy SE 7.1 PCI card) and driver version (windows 7 64-bit driver) reproduces the problem on a system where the OS is Windows 7 64-bit (amd64/X64)?

Reports of this happening on Windows XP are not helpful to me because (1) I do not have Windows XP on any PCs I use, and (2) the DirectSound implementation in the OS changed between Windows XP and Windows Vista.
