Dell 5070 ThinOS 9.0.3 USB Headset Citrix Virtual Apps

Hi All


I’m looking for some assistance with a USB Headset not working on Dell 5070 ThinOS terminal.



  • Dell 5070 ThinOS running version 9.0.3
  • Citrix Farm is Windows 2012 R2 running 7.15 LTSR CU4
  • I have enabled on the Citrix Policies the following:
    • Audio over UDP real-time transport – Enabled
    • Audio Plug N Plug – Allowed
    • Client Audio redirection – Allowed
    • Client Microphone redirection – Allowed
    • Client USB device optimisation rules, the the below entry set
      • Mode=00000002 VID=0x0572 PID=1434 class=01 #SOUNDSHIELD UC20 connected
    • Client USB device redirection – Allowed


On the device using WMS I have:

  • Under Broker & Session enabled Enable UDP Audio
  • I'm not excluding Audio or Video device


The headset works on Windows 10 using Receiver v18 when connecting into XenApp. I have installed Fedora on a laptop and configured Citrix Receiver 2006 for Linux with USB support package as well, on Fedora I get the sound coming from the headset but no mic and when viewing “devices” inside the Citrix session, I do no see the headset at all. The sound is showing “Citrix HDX audio”. So it would seem that the Citrix Policies are working OK.


When connecting to XenApp through the Dell Wyse 5070; inside the Citrix session under “Devices” i see the headset as device but no sound when trying to play sound or when trying to record audio through the microphone there is no recording. XenApp detects the sound as  “Citrix HDX audio”


The headset works outside of Citrix when testing on 5070, Fedora and Windows.


If I use a headset with a 3.5mm jack instead of USB all works fine on XenApp. I also have a USB webcam which is working without a problem.


Any other suggestions?


Thanks Jason
