A new (apparently somewhat major) IDT sound driver update has been released by HP. This update was released in two separate packages, one for 32-bit systems and one for 64-bit. My package, as usual, contains support for both. Additionally, one .DLL file, "stcplx.dll", was removed from the driver package. The driver still appears to install and work correctly without it, however. You can get more information and download the driver here.
