Hello,
With Windows 10 1809 I am trying to pass the HLK Audio Tests with our
device. I am getting an error on the Audio Engine Core Test (UMACoreTest)
complaining:
UMACore::Tc_KSRenderEndpointGetFrequency
SetBuffer with 100000 returned 0x887c0054
SetBuffer with 101584 returns 0x80070057
The first SetBuffer is failing with AEERR_BUFFER_SIZE_ALIGNMENT_ERROR which
is normal.
The second SetBuffer is failing with E_INVALIDARG, which is the cause of the
failure.
Our driver NEVER returns E_INVALIDARG anywhere, and the call to
AllocateBufferWithNotification is always returning STATUS_SUCCESS.
What could be causing this failure?
Thank you,
David A. Hoatson
