Microphone not working

USB Docking Stations UD-3900H
1

Hi

On my laptop, under Windows 10 pro, my microphone doesn’t send any sound to windows, but it is detected.
I’ve tested the mic on my other pc (MSI desktop), win 10 family, and the mic worked great.

How can I either activate the mic port, or boost the volume?

Hi Hugues,

Thank you for contacting Plugable! I’m sorry to hear the UD-3900H isn’t working as expected, but I’ll be happy to assist.

As a first step we’ll want to ensure that the Microphone jack from the UD-3900H is set as the Default Recording Device in Windows. To do so, please follow these steps:

  1. Check that your device is properly connected, and that any necessary drivers are installed
  • It is also a good idea to make sure that your sound device is turned on, and that the device’s volume control is not at the absolute minimum setting
  1. Right-click on the speaker symbol in the Windows taskbar/system tray
  • Select Open Sound Settings then click the link under ‘Related Settings’ for Sound Control Panel, then click the Recording tab
    Accessing sound preferences in Windows 10 or 11
    • Alternatively, after selecting Open Sound Settings, use the dropdowns under the Input header

  1. Find your device in the window. UD-3900H’s microphone jack will appear as Plugable Audio

  2. Right-click on the device you found in step 3 and select Set as Default Device. A check mark should appear next to your device, and sound should now play through it

  3. Click OK to exit the window

Once these steps are complete, the microphone connected to the 3.5mm analog audio input jack on the UD-3900H will be set as the default input.

In case you’re curious, we have these steps for Windows 10/11 and various other operating systems available as an FAQ here: https://kb.plugable.com/question/379342

  2. While the UD-3900H is connected to your PC with the microphone plugged in (even if not working as expected), the output of our diagnostic utility PlugDebug: https://plugable.com/pages/plugdebug
