No audio through USB-C Dock

Running latest stable on a Dell Latitude 7410 that is connected to to an external monitor via a Dell WD19DC dock using twin USB-C connections. Everything else (video and controls) pass through the dock as they should but I can’t seem to get audio to go out.

Any advice?


  1. Please read this:
    How to provide good information
    and press the three dots below your post and press the :pencil2: to give us more information so we can see what’s really going on.
    Now we know the symptom of the disease, but we need some more probing to know where the origin lies… :grin:
  2. An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information for us to be able to help you. (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
    Also, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text.
  3. please perform the inxi above twice:
    • without the dock (working sound?)
    • with the dock (not working, right?)


P.S. If you want to notify me that you did provide this information, please :heart: this message and I’ll come back and have another look.
