Thinkpad Thunderbolt 3 dock - delayed audio

I have a Thinkpad Thunderbolt 3 Dock that is docked with a T480s. When using the 3.5mm audio port on the dock, audio is delayed about 150ms. I have tested with different speakers and headphones and the result is typically around 150ms delay when using the audio jack on the dock.

 

I have everything updated via Lenovo Vantage and am currently using Windows 10 x64 1803, The test was performed via this youtube clip: https://www.youtube.com/watch?v=ucZl6vQ_8Uo

 

Things I've tested:

  • Headphones/speakers connected to 3.5mm in dock - ~150ms audio delay
  • Headphones/speakers connected to 3.5mm in dock (turned off dolby) - ~150ms audio delay
  • Headphones/speakers connected to 3.5mm directly to T480s - no audio delay
  • USB headphones connected to dock - no audio delay
  • USB headphones connected to t480s - no audio delay

I'm having the same issue with the USB C dock.   Anybody had any luck resolving this?

Subscribing because I was looking to buy a fleet of X1 Yoga 3rd gen along with the Thunderbolt dock. This would be problematic..

I'm having the same issue with the Thunderbolt dock 3, X1 Carbom 6th gen (Win 10 64 Pro). All drivers is updated, including latest BIOS. Delay on 3.5 jack is about 150-200ms.

Yes, same issue here with the thunderbolt Dock and Carbon x1 laptop. All was good until fairly recently, within the last few weeks to a month I started noticing it.

Same here with my X1 Yoga 3rd gen. Any mods who can help look into or direct to engineers this issue?

Same issue here.  T580, 20L9-001MUS, Win10 1803, clean install with latest drivers and firmware for laptop and dock.  Audio delay happens on the thunderbolt dock headphone jack, but not on the headphone jack on the laptop itself.

 

I'm running an LG 34" monitor on my thunderbolt dock's displayport connection.  There is no delay if I sent the audio to it.  The delay only appears when I run the thunderbolt dock's headphone jack.

Re: Thinkpad Thunderbolt 3 dock - delayed audio

Sounds like an issue with the dock's processing then, and not Thunderbolt.
