Hi, Matt,
Ok, I just tried those interfaces and mediums but no
change....
I had tried a similar variation earlier...and after it
did not work, I convinced myself that I did not need
it...
Here are my updated pins...SysAudio is relentless. It
still gives me 0xC00000BB.
{
&AudioCapturePinDispatch,
NULL,
{
SIZEOF_ARRAY( waveinterfaces ),
waveinterfaces, // Interfaces
(NULL, 0 == default)
SIZEOF_ARRAY( wavemediums ),
wavemediums, //
Mediums (NULL, 0 == default)
SIZEOF_ARRAY( AudioCapturePinDataRanges ), // Range
count
AudioCapturePinDataRanges,
// Ranges (filled in
later)
KSPIN_DATAFLOW_IN,
// Dataflow
KSPIN_COMMUNICATION_BOTH, //
Communication
&KSCATEGORY_AUDIO, // Category
//&KSNODETYPE_SPEAKER, // Name
&g_PINNAME_AUDIO_RENDER, // Name
0 // Reserved
},
KSPIN_FLAG_PROCESS_IN_RUN_STATE_ONLY |
KSPIN_FLAG_FIXED_FORMAT,
1, // Instances
Possible
0, // Instances
Necessary
&AudioDefaultAllocatorFraming, // Allocator
Framing (filled later)
reinterpret_cast <PFNKSINTERSECTHANDLEREX> //
Intersect Handler
(CAudioPin::IntersectHandler)
},
// Audio Capture Pin: AUDIO_PIN_CAPTURE
//
{
&AudioCapturePinDispatch,
NULL,
{
SIZEOF_ARRAY( waveinterfaces ),
waveinterfaces, // Interfaces

wavemediums, //
