Installing XP WDM Drivers for the Terratec EWS88MT Audio System

Posted August 2002 by Steve Sinchak

After Loading XP you will see "Multimedia Audio Device" with an unidentified icon in Device manager. When loading the Terratec Drivers you will get an error message saying the drivers are not signed.

  • click ignore, install anyway -

then you will get an error message saying the install was not completed due to a part of the .inf being invalid and device manager will show about 10 unidentified new components (your SystemWave through Audio 1 to 8)


wait 30-45 seconds and the system will rescan itself and one by one the devices will disappear, once you are back down to one Unidentified Multimedia Audio device reload the drivers again.

This time they will install properly with no errors and you will have all the proper audio channels for your system.

Driver Updates to the 5.0 WDM version can be found at
