OK … sadly that’s no good news
Currently I think my problem is around this output from KS Topology Filter

But yet I don’t know the relationship from the USB Driver struct to the
processing modes – why does the Linux audio gadget have the support of
processing modes set or in other words what entry in the USB Tree View lets
windows activate the processing modes for this device?

For various dry and boring technical reasons I find myself unable to update
this blog post with new Windows OSes.

Yes, thanks … I already found this link today and grabbed the TMF files from
your github page. Do you think it’s possible to also add the ausbaudio2 tmf
files for W10 21H1 there?
