WDM and MME
In most situations, the newer WDM (Windows Driver Model) sound card drivers that most sound
card vendors are creating are a much better choice than the older MME (Multi-Media Extensions)
drivers. If your sound card vendor has a WDM driver, it’s usually a good idea use it. The following
table compares their characteristics:
IRQs
An IRQ (Interrupt Request) is an assigned location where the CPU expects to be interrupted by a
device when it has completed a task. There are 16 IRQs on a PC. Usually, three or four are taken by
the system, leaving 12 or 13 for other devices, like printers, USB devices, hard disks, floppy disk
drives, keyboard and sound card. Some of these devices can share an IRQ with other devices, but
for the most part this is not a good thing, and for a sound card which can use a lot of CPU power, it
WDM MME
Lower latency Usually higher latency
Works with Windows 2000, ME, 98
SE, but not 98 Gold
Works with Windows 98, and ME. Some MME drivers may work with
Windows 2000.
Not every sound card vendor has
produced a WDM driver.
MME drivers are widely available.
Note: If you use two or more sound cards at the same time, and not all
of them have WDM drivers, you must force the WDM drivers to function
as MME drivers. Do this in the Audio Options dialog box (except in GT
Pro) on the Advanced tab by checking the Always Use MME Interface
Even When WDM Drivers Are Available check box.
In GT Pro, see the README document that came with your software.
