Hello, I recently installed my Thunderbolt 4 AIC, but the DP-pass-through doesn?�t work correctly.
When I connect my Anker 8-in-1 hub (HDMI output) or my Viture One Glasses directly to the card the displays are working fine, but if I try to use my CalDigit ElementHub (Thunderbolt 4) the displays do not get recognized. The ElementHub is correctly shown in the Thunderbolt control center and works as expected with my laptop and my phone.

My setup is a ASRock LiveMixer AMD B650 (Bios 2.02) with an AMD 7800X3D and a Nvidia 3070 Ti running Windows 11 Pro. I have the latest available AIC driver (Rev81) installed. I have my 3070 connected to the first DP-input and the AMD-internal-GPU to the second.

How can I trace the issue further?
