D1 troubleshooting tips


The following troubleshooting tips can help diagnose and correct most common issues with the D1.  We have attempted to make this list as comprehensive as possible, so some of these may not apply to your issue, but please go through each tip and if the problem still persists then open a support ticket here


Be sure to include your results and we will then respond as quickly as possible and do our best to resolve the issue.

  1. Restart your computer and make sure your computer’s OS and all related apps are up-to-date.
  2. Make sure the USB cable and audio cable connections to and from the D1 are complete and verify that these cables are in working order by unplugging the cables and then reconnecting.  Try using the included USB cable if you are not already.
  3. It is important to note that the USB audio input will only work with a computer.  If you are attempting to use your D1 with a different device the USB port is only used for power and not audio.
  4. Remove all other USB devices temporarily from your computer to see how this affects the D1 playback.  Audio over USB and bus powering a device can both be somewhat demanding.  USB ports can share a bus internally and can also share their bus with devices internally as well.  Because of this, some ports may not perform as well as others, so be sure to try each USB port one at a time.
  5. If using Windows, uninstall the USB driver from your computer.  Then disconnect the USB cable to remove the D1 from your computer and plug it back in to allow the driver to re-install automatically.  You can find complete instructions from Microsoft on how to reinstall a plug-and-play device under Windows here.
  6. If you are using a Mac, try a NVRAM/PRAM reset.  This resets the system configurations for some audio and video related things and can many times help clear up problems related to audio.  See Apple’s support page for information on how to do this.
  7. Try music with different bit depths and sample rates.  On a Mac these settings are under Applications --> Utilities --> Audio MIDI Setup.  Try using both 16-bit as well as 24-bit settings.
  8. Experiment with using a different media player (iTunes, Songbird, WinAmp, Cog, etc) and different audio file types (MP3, ALAC, FLAC, etc).  And if your media library is located on an external drive or network attached storage (NAS), try playing audio files on your internal local hard-drive.
  9. If using the optical input on your D1 be sure that your source device (computer, TV, CD/DVD player, etc) is set to PCM Stereo output and not Dolby Digital or DTS.
  10. If you are using a wireless device with D1, temporarily remove the wireless adapter from the setup and connect the D1 directly to the audio source.
  11. Try your D1 with a different computer to see if something is causing an issue in the current setup.
