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
