2 different computers: Kernel streaming and »Error starting device playback«

This problem has been with me for years now, literally.

Windows 11, 8 GB laptop, DACs S.M.S.L SU-1 or Topping D-10

No matter what DAC, when trying to playback with Kernel streaming, I run into »Error starting device playback« everytime.

What is new now:

I installed Audirvana Studio on my big desktop computer (Windows 11, 32 GB) and connected the two DACs to it. And what a surprise: Not the slightest problem here to do playback with Kernel streaming.

My question now: Inspecting the latest Debug Info files, the one from the laptop and the one from the desktop computer, what differences should I find that could point me to what the problem is, whatsoever?
