Creative’s Xmod audio enhancer delivers virtual 5.1 surround sound to your headphones or speaker pair. It’s a great little device. Unfortunately, its default settings on the Mac do not let you experience all the great 5.1 sounds you should be hearing.

Here’s how to fix that.

1. Connect the Xmod to your computer and your speakers or headphones to the Xmod.
2. Open /Applications/Utilities/Audio MIDI Setup. This application lets you tweak the system settings for your input and output devices.
3. Select Creative Xmod from the Default Output pop-up.
4. Select Creative Xmod from the Properties For pop-up list.
5. Click Configure Speakers. This is a rectangular button to the right of the Clock Source. A settings window opens.
6. Click MultiChannel. You’ll find this button at the top-left.
7. Choose 5.1 Surround from the pop-up at the top-right.
8. Click Apply.
9. (Optional) To test any of the virtual speakers, click the rectangle with the speaker name. A brief white noise will sound from that “speaker”.
10. Click Done.
11. Your configuration is complete. You may quit from Audio MIDI Setup.
