Windows 10: USB-C docking station audio issues

Hi all,

I'm stumped by this one. So I bought a USB-C docking station and everything works fine except the audio. When I plug my external speakers into the 3.5mm jack, they work fine. BUT, when I plug in an external monitor via HDMI, they no longer work - the audio defaults back to the laptop speakers. The really weird thing is that the audio device disappears when I do this (see screenshots below).

I've dug around for a while, and haven't been able to find anyone else with the same issue. I'm wondering if it's a problem with the dock itself (which admittedly is a cheap-o from Amazon) or if this could possibly be a Windows 10 issue? Any help would be appreciated!

:)

Audio not working through a docking station

This is happening for me as well on my Surface Pro 3. Audio plays through the Dell D3100 USB docking station when docked on the SP3 docking station. I take the surface off the docking station and the audio switches to Surface built in speakers. When I
re-dock the surface, the sound continues to play through the Surface despite the Audio playback devise settings suggest the sound should be coming through the Dell D3100. The issue persists after attempting to re-assign the default device. The only way
that I have found to correct this is to reboot the surface while docked but it all goes to **** once the Surface is removed from the dock.

- This system was upgraded from Windows 8.1 (Issues did not exist in Windows 8.1)

- 8.1 DisplayLink drivers removed and updated to version 7.9.296.0

 

No audio from USB 3.0 docking station

I connected a DL-3xxx or DL-5xxx based USB docking station to my PC via a USB 3.0 cable and found that the audio will not play through my speakers attached to the docking station. I've been told that
this is an issue with the inbox USB 3.0 driver in Windows 10. I would appreciate it if you could provide a fix for this.
