Dear All:
I found out a new problem about the KsStreamPointerDelete function.
The error is only happened on new Intel 865G/915G motherboard.
Moreover, I also need use the source filter from Audio Capture Sources folder.
When I put the KsStreamPointerDelete during a spin lock stage, the windows
system will be crashed by this code.
KeAcquireSpinLock( &pStreamPin->m_oStreamPointerAccessSpinLock, &eIRQL );
KsStreamPointerDelete( pCloneStreamPointer );
KeReleaseSpinLock( &pStreamPin->m_oStreamPointerAccessSpinLock, eIRQL );
If I don't use spin lock, the function can be called successfully.
It is a strange problem and only is happened on new Intel framework.
Best Regards,
H.P.
