  If USB devices aren't working when plugged into your NEC Switch IntelliBase, consider these potential causes: * Ensure the USB cable connecting the IntelliBase to your computer is properly connected and not defective. Try reseating the cable or replacing it. * Verify that you've plugged the USB devices into the correct USB ports, specifically the output ports on the right side of the IntelliBase. * Check if the USB devices work when directly connected to the host computer to rule out issues with the computer or its software. * Try using a different USB device with the same output port to identify if the problem is with the specific USB device.

  If the USB audio from your NEC Switch is distorted with static, crackling, or hissing, it could be due to the volume level or input signal from the sound file being too high. Try turning down the volume on the IntelliBase or using the control panel software GUI.

Why is the analog audio distorted on my NEC Switch?

  David JosephAug 8, 2025
  If the analog audio from your NEC Switch is distorted, producing static, crackling, or hissing sounds, it could be due to several reasons: * The speaker may be overdriven by an amplified audio source. Ensure the IntelliBase is connected to the line-out jack (unamplified) of the sound card, not the speaker-out jack (amplified). * The volume level on the sound card or audio source might be too high, causing the speakers to be overdriven. Check and lower the volume as necessary. * The sound card or the specific file/track may be the source of the problem. Test the speakers with another audio source, like a CD-ROM player, to isolate the issue.
