HLK Audio Engine Core Test (UMACoreTest) failure RRS feed

  • Question

  • 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
