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
