No, I have not tested the HLK yet.
It is not currently possible to enter DispatchProcess and the leading
edge stream pointer cannot be obtained.
I think the current driver function is not complete, so the HLK test
has not been done yet.
引述 Matthew van Eerde <dmarc-noreply@xxxxxxxxxxxxx>:
Have you run the HLK tests?

Subject: [wdmaudiodev] AVStream audio render issue
Dear all,
I am developing an audio render using AVStream.
It is now correctly displayed on the Playback Device.
Then I used Graphedit to test.
When the render filter in the "Audio Renderers" category is selected,
the DispatchProcess of the pin is not called.
I suspect that the pin did not receive the data, so the
DispatchProcess was not called.
But if I use "WDM Streaming Rendering Device" then everything works fine.
I have confirmed that the state of the pin is already "KSSTATE_RUN".
Please help me solve this problem, thank you.
Here is the pin DESCRIPTOR for this driver:
static
const
KSPIN_DESCRIPTOR_EX
ksCaptureFilterPinDescriptors[] = {
{ //Audio Input Pin
&ksCapturePinDispatch, // Dispatch
NULL, // AutomationTable
{ // PinDescriptor
DEFINE_KSPIN_DEFAULT_INTERFACES, // Interfaces
DEFINE_KSPIN_DEFAULT_MEDIUMS, // Mediums
SIZEOF_ARRAY(ksAudioPinDataRanges), // Range Count
ksAudioPinDataRanges, // Ranges
KSPIN_DATAFLOW_IN, // Dataflow
KSPIN_COMMUNICATION_SINK, // Communication

&KSCATEGORY_AUDIO, // Category
