I have USB 3.0 to HDMI 4K graphics adapter running LG monitor, Windows 7. Graphics fine, but no 3-UGA-4KHDMI audio drivers setup. How can I get the sound working. DisplayLink install says all good. Thanks! Joe
Hi Joe,
Thank you for reaching out to us, I am sorry this is not working as expected.
I would like to start by verifying the audio device is detected inside of Windows, please perform the following:
- Right-click on the audio icon in the Windows System Tray ( lower right corner of the screen )
- Select “Playback Devices” from the pop-up menu
- Look for the option: “Speakers - DisplayLink USB Audio Adapter”
- Right-click on the option from step 3 and select “Test” - this should play a test tone
- Right-click on the option from step 3 and select “Set as default device”
If the tone does not play in step 4, please let me know the model number of the monitor so I can verify it has built-in speakers ( not all monitors with HDMI inputs have built-in speakers ).
Thank you,
Pat

Hi Pat,
Thanks for responding. My problem is the DisplayLink USB Audio driver did not install when I installed DisplayLink video. Video is fine. No driver for audio.
Yes, my LG 43UD79-B monitor has speakers.
What’s the trick
Thanks!
Joe
Hi Joe,
Thank you for getting back to me!
Our next step is to reset the adapter and perform a ‘clean’ installation of the required DisplayLink drivers to help ensure both are in a good state. Please perform the following:
- Disconnect the adapter from the system so it turns off completely (this is important so the unit resets). Please keep it disconnected until the last step.
- 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, just move onto the next step
- Download and run the DisplayLink Installation Cleaner utility, found here –> https://s3.amazonaws.com/plugable/bin… and ensure it displays “Cleaning Complete” when done (video walk-through if you need it -> https://youtu.be/AcVV1gD_FvI)
- Once the Cleaner has been run, reboot (even if not prompted to)
- Now download and install the 8.4 M2 DisplayLink software, found here –> https://s3.amazonaws.com/plugable/bin…
- Reattach the USB graphics adapter to the computer. If the device is not detected, please reboot the system.
When completed the device manager should look like this:

To access the device manager, start by opening the Start Menu, right-click on computer > Manage, then selecting Device Manager on the left.
Please let us know if that helps get things working how they should, and we’ll go from there.
