Dear All:
I am developing an audio driver which is based on Streaming Minidriver
framework.
When I use the filter within "WDM Streaming Capture Devices" category, the
audio stream (44100MHz) is listened well.
However, when I use the filter of "Audio Capture Sources" folder, there is a
serious delay (1 ~ 2 secs) which is happened.
I don't know what's happened in this delay.
The filter within "Audio Capture Sources" folder is a virtual filter, right?
Why can't the MasterClock be offered from DirectShow manager for this filter?
Can you help me to solve this problem?
Best Regards,
H.P.
