Dear All:

I have written an audio AVStream driver.
It registers successfully an audio capture filter into two different
categories, Audio Capture Sources and WDM Streaming Capture Devices.
The capture filter, which is in WDM Streaming Capture Devices folder, is
workable well for any operations.
However, when I use the corresponded filter within Audio Capture Sources,
there is serious problem below:
I can listen the sound from this filter, but I can't stop it.
When I push the "stop" button, the graphedit will be blocked!!
The OnPinClose function cannot be called by directshow in my driver.

Can you help me?

Best Regards,
H.P.

1) what AVStream sample did you use (DDK version) ?
2) i use 3790 DDK Build, and i can't do what you have done - I can't
register my filter in Audio Capture Category. Please help! I have read 2
topics: AVStream : raw audio pin & Second topic where Igor Slewsarev posts 2
messages about it (can't find topic name right now). where to start finding
problems ?
