Logitech c920 mic not working with docking

[Francoisl]

Hello,

I’ll explain the situation.

I have a logitech Webcam C920 that is connected to my docking (CADUAL4KDOCK) via a system "usb extend TY5 techly".

- Webcam connected in USB on Extender 1
- From extenter 1, an ethernet cable that goes to Extender 2
- The extender 2 is plugged with USB on the docking

The image works, but not the mic..

Here’s what I tested:

- If I connect the extender 2 directly to my PC, the webcam mic works perfectly (I can’t leave it like this, as it bothers the user)

- I tried to connect to another i-tec docking model -> The problem still present

- I tried to connect another PC to the doc i-tec -> The problem is the same

- I tried to update the Display driver -> The problem still present

- I reinstallated the device in device manager and reboot the computer -> The problem still present

- I reinstalled the webcam driver and reboot the computer -> The problem still present

- I checked if the mic is already activated in micro settings -> Already Activated

- I checked if the mic has the rights to be activated -> Rights ok

To resume, Mic issue happens when its plugged on docking, It's don’t care about the computer or the docking.
But the microphone works if it is not connected to the docking

Please help me
