X1 Carbon 6th Gen & Thunderbolt 3 Gen2 Dock - Garbled Audio/WebCam

2020-09-18, 21:50 PM

I have a persistent issue with my X1 6th Gen 20KH002JUS.   I purchased two new Thunderbolt 3 Gen 2 docks and have the same issues with both of them. The TB 3 Gen 1 dock seems to not have the issue.

 

My Logitech 920C camera and also System to 3.5MM out audio are garbled and the camera output is garbled.  Input direction is fine.  The webcam and audio are fine when I output directly from the laptop either via 3.5MM or the USB 2 port to the devices.

 

The TB Software on my laptop is 17.4.80.550, controller driver version 17.4.80.94, and NVM Firmware of 45.00.

 

The dock is also running the latest drivers from the V10015 package in Sept 2019. And the firmware from the 3.1.67 update in July 2020.

 

I've tried to completely uninstall and re-install all devices, but it didn't help.

 

Thanks for any help

 

Kurt

Update based on another post read in the forums.  I tried to use the HID generic driver with no success.   I turned off USB Power Save per this article and the problem dramatically improved.  I now receive a glitch or flicker once per 15-30 seconds rather than almost continuous.  Sadly, I will still need to keep the camera plugged directly into my laptop - and 3.5mm out audio from the dock - no solution.  https://www.tenforums.com/tutorials/108194-add-usb-3-link-power-management-power-options-windows.html
