Speaker and HDMI failure

The audio plug (mic) failed and now the DVI link to the monitor has also failed. The docking station is not that old, purchased less than 12 months ago and I am loath to pay for a replacement. I have checked both the audio link and the video link from the other end of cables and they function correctly. The problem seems to be in the docking unit. Any suggestions?

Hi Crawford,

Thank you for posting! I am sorry things have stopped working as expected with your UD-3900 docking station and I would be happy to help.

We offer a 1-year hardware warranty for all products sold by Plugable and fulfilled by Amazon. If your purchase meets those requirements, should ultimately it be determined necessary we will of course provide a replacement under warranty.

However, we will first want to do some quick troubleshooting to help rule out other factors that would cause a replacement to behave in the same manner.

Based on your description of the behavior, our first step is to completely reset the dock and perform a ‘clean’ manual installation of the latest version we recommend of the required DisplayLink driver to help ensure both are in a good state. To do so, please follow these steps:

  1. Please disconnect the dock from the system and please disconnect the power cable from the dock so it turns off completely (this is important so the unit resets). Please keep everything disconnected until the last step.
  2. Uninstall any and all software with ‘DisplayLink’ in the title that is present from within the Control Panel -> Programs and Features. Don’t worry if these entries are not present or if the process does not work, please just move onto the next step.
  3. Download and run the DisplayLink Installation Cleaner utility, found here --> https://s3.amazonaws.com/plugable/bin/DisplayLink/DisplayLink+Installation+Cleaner+9.1.1462.exe and ensure it displays “Cleaning Complete” when done (video walk-through if you need it -> https://youtu.be/AcVV1gD_FvI)
  4. Once the Cleaner has been run, reboot the system (even if not prompted to).
  5. Now download and install the 9.2 M3 DisplayLink software driver, found here --> https://plugable.s3.amazonaws.com/bin/DisplayLink/DisplayLink+USB+Graphics+Software+for+Windows+9.2+M3.exe
  6. Reconnect the power cable to the dock first. Once the dock is powered on (a blue light will be present on the front), reconnect it to your system. If the device is not detected, please reboot the system.

Please let us know if that helps!

Thank you,

Bob
