This is the original first release WDM driver for the DIO 2448 intended for use with Windows 98SE, ME, and 2000 only. Subsequently installation in XP is possible with this pre-XP release driver.

Windows XP Users please note:

Windows XP will install its own files for the Crystal Audio chip found on the DIO-2448 from the driver cab archive that is part of Window XP system files. There is no way to install the M-Audio drivers in place of this.

SPDIF Output will not be available. MME will function for Media Players and MME sound applications such as Sonar, Sound Forge, etc…

To add ASIO support do the following:
1) Download this driver
2) Extract the files to a floppy disk or to a directory.
3) Go to Device Manager and open the \\\”+\\\” sign for Sound, Video and Game Controllers.
4) Select the Crystal Audio Soundcard.
5) Select Properties and Update driver.
6) Point the Windows Update Wizard to the floppy disk.

Once this is complete, the DIO-2448 will now support ASIO.
