Displaylink 7.8/9 and issue with HDMI audio

Makky · 10-20-2015, 01:11 PM

Hi,
I am using a HP 3005pr USB docking and Win 7.
After I updated the Displaylink software, first testing 7.9, then 7.8, my HDMI audio stopped working. If I connect through an Displayport-adapter, sound works.
Also, If I use 7.7, HDMI audio works.

Anyone got a culue on what's the issue?

IF I open the "Playback devices", I se the "USB audio"-device and I can see sound is "playing" on the device, but as said, no sound is comming.

The USB docking has both HDMI and Displayport, and sound works if I connect the HDMI cable with a Displayport adapter.

Hi,

Thanks for reaching out.

Can you check that the USB audio is set to be the default playback device?

Please see attached image showing USB audio set as the default playback device.

Thanks,
James
