Hi all, In MSVAD, each stream has its own timer for simulating IRQ. Is there a fundamental reason why a single timer could not be shared between the render/capture streams ? I note that in TimerNotify, the miniport object's Notify method is called. Thus, with render and capture stream, it would be called twice for each Interval, right ? Seems a bit unnecessary to me...
