Hi Jerry,
thanks for your reply. I already found your post and I followed the idea using
.bFunctionSubClass = UAC2_FUNCTION_DESKTOP_SPEAKER. So far I didn’t check the
USB_ENDPOINT_SYNC_SYNC as I think this link
https://docs.microsoft.com/en-us/windows-hardware/drivers/audio/usb-2-0-audio-drivers?source=docs
in combination with USB spec 2.0 chapter 5.12.4.1 suggests that
USB_ENDPOINT_XFER_ISOC | USB_ENDPOINT_SYNC_ASYNC is correct. Unfortunately I
don’t have any USB device here that uses usbaudio2.sys. Either they have native
drivers or they use usbaudio.sys. Otherwise I could compare the USB Tree View
output from a working device to my Raspberry.
Best,
Johannes

Hello Johannes
ICYMI See https://www.freelists.org/post/wdmaudiodev/Linux-UAC2-gadget,1 for ;
some details on a then working UAC2 gadget. This may or may not help with your
particular problem:)
Good luck
Jerry.

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

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

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?
