KsPinGetReferenceClockInterface Unsuccess Issue

Hi All,

I had implemented the AVStream driver to register our audio capture filter into two categories, “WDM Streaming Capture Devices” and “Audio Capture Sources”.

When I used the driver from “WDM Streaming Capture Devices”, during KSSTATE_ACQUIRE, I can obtain the clock interface from KsPinGetReferenceClockInterface. However, if I use the filter from “Audio Capture Sources”, the KsPinGetReferenceClockInterface will return fail. The

Do you know how to fix it?

Many Thanks.

There is nothing to fix. If there’s no master clock, then you provide your own timing.
