Thanks, I have conveyed that information to the developers.

You could certainly open a support case if you wanted to expedite things. If 
you do, please tell the support engineer this is about “OS bug 13834139.”

Let’s see…

Yes, the devs have asked if this repros on the latest Insider build (currently 
the latest Insider build is 16299)


Yes, it’s exactly the same behavior with Insider build 16299. Should I probably 
open a support incident to get in contact with the developers?

Subject: [wdmaudiodev] Where to report issues with the Windows 10 UAC2 audio 
driver?

Hi all,

I am investigating compatibility of our USB Audio Class 2 devices with the 
latest Windows 10 UAC2 driver v10.0.15063.502.

With most of our devices I see very weird behavior of the driver on the USB: 
there is an endless sequence of the following requests

* Set Samplerate
* Set Alternate Setting 1 (enable audio streaming)
* Set Alternate Setting 0 (disable audio streaming)

What is the best way to report this issue to the Microsoft driver developer(s)?

Additionally, the driver does bundle all channels of a device into only one 
WASAPI device. Therefore, a user cannot select e.g. the headphone output as his 
standard audio device. Is there some documentation available on how the UAC2 
driver derives the WASAPI architecture from the devices USB descriptor?

It seems that there is still very little documentation for this new UAC2 driver 
on MSDN, every hint is very welcome!

Best Regards,

Franz
