In your submission readme.txt, cite errata 511 for this failure, which will 
prompt a manual review of the submission. This looks like test bug Windows Blue 
Bugs 17160 to me.

Subject: [wdmaudiodev] DTM Test on USBAUDIO.SYS with a custom INF, with Windows 

I am trying to pass the DTM audio test on an USBAUDIO device with a custom INF.
My custom INF :
 - Includes wdma_usb.inf
 - Calls the USBAudio sections to install the usbaudio driver
 - Add a custom LFX APO dll

It seems that WaveTest.exe does not recognize my driver as usbaudio.sys and try 
to pass this test : Reset Pin while streaming data. This test fails because 
USBAUDIO.SYS is not a port class driver and does not support the 
WaveTest output :
FAIL: Pin has not responded to IOCTL_KS_RESET_STATE command for KSRESET_BEGIN 
correctly. Position after reset is not zero
When I start the same test with the standard wdma_usb.inf installation, 
WaveTest write:
The driver used is a known non-portcls driver: wdma_usb.inf.
IOCTL_KS_RESET_STATE is not required to be supported by non-portcls drivers
And the test is skipped.

I tried to apply the DTM Filters, there is a DTM filter related to this issue 
https://sysdev.microsoft.com/fr-FR/Hardware/EC/FilterDetail.aspx?id=271) but it 
is only for the capture pin, not for the render pin.
Have you any idea how to pass this test with a custom INF?
