Displaylink Shuts Off Sound in Win 8.1
 

I am having an issue with my DisplayLink USB2.0 External HD Adapter with Windows 8.1. This is a brand new machine with Windows 8.1 pre-installed. The monitor works fine....it just shuts off the sound. The sound returns when I unplug the USB cable to the adapter. (Please note that the setup worked fine, sound and all on my previous Windows 8.1 pc). Here is what I'm running:

Dell XPS8700
CPU = i7-4770 @ 3.40GHz
24 GB RAM
64-Bit Operating system
Audio: Integrated 7.1 with Waves MaxxAudio
Windows 8.1

I ran the DisplayLink cleaner tool and rebooted.
Device manager calls the device: USB Display Adapters: USB to HDMI
Program Manager shows:
DisplayLink Graphics version 7.6.55705.0
DisplayLink Core Software version 7.6.55673.0

Thanks for looking at this!

Hi,

When you connect the adapter does default audio playback device change?

Thanks,
James

Hi James. Thanks for responding. Here is what's in my device manager:

Audio inputs and outputs:
1 Dell S2409W
Microphone (Webcam C260)
Speakers (Realtek High Definition Audio)
Speakers (USB to HDMI) *** this is present when DisplayLink connected, absent with not connected

Sound, video and game controllers:
AMD High Definition Audio Device
Realtek High Definition Audio
Webcam C260
USB to HDMI *** this is present when DisplayLink connected, absent with not connected

***** Issue resolved. I went into the Control Panel under Sound and chose the Realtek High Definition Audio option. Thanks for directing me there! *****
