4. Configure your sound card

To use your Matrox RT.X100 Xtreme, you must have a DirectSound-compatible

16-bit sound card installed and properly configured with the latest drivers. For

information on installing your sound card, see the documentation that came with

your card.

If your system has on-board audio, and you want to install a separate sound card,

you’ll have to disable the on-board audio in your system’s BIOS. For details on

how to do this, see your computer’s documentation.

For information on supported sound cards, see the RT.X Support section of our

web site at www.matrox.com/videoweb/support.
