Kernel Streaming Not Working in Windows 11

[Skyrider]

Hi,

Currently running Studio 2.3.0 in Windows 11.

For some reason I am unable to use Kernel Streaming in Windows 11. It can be selected, but the track will not play & there is no sound output from the internal speakers.

It used to work okay, I do not know at what point it stopped working.

I have uninstalled/reinstalled but the issue remains

Did you get a sound driver update? It’s strange it used to work and without an update from us, it’s not working anymore.

[Skyrider]

The driver for the internal speakers is listed as version 10.0.22621.1 dated 06/05/2022, with no update available.

FYI: Kernel streaming is working okay when routed through my external DAC (iFi NEO iDSD).
