You probably have a reference count problem. For example, assume your
topology filter doesn't go away because it was not properly cleaned up.
A lot of the objects listed below might all belong to this port. The
best thing is to dds some of the leaking objects to find WHAT is
leaking. The tag doesn't help you that much here.

OK, I finally narrowed it down somewhat. This only happens if I call
PcRegisterPhysicalConnection between my waveout pin and my topology in
pin.
Note that for now I don't expose a MUX or record controls in my
topology,
even though I have record capability (through ASIO). So I only call
PcRegisterPhysicalConnection once for now. Note also that I have no
problems under WinXP SP1.
If anyone has any further thoughts on this, I'd be interested. Thanks
in
advance,
Philip Lukidis
