If you dump the endpoint properties for this device (with the Conexant driver)
do you see a PKEY_AudioEndpoint_Supports_EventDriven_Mode property with value 1?

Further to this, just for the heck of it, I uninstalled the Conexant device,
and during the driver installation procedure, I skipped Windows update so that
the Microsoft HDAudio.sys was chosen instead, and then the code works fine. A
workaround, but not good, since the Conexant driver does work in Windows 7, so
I'd like to be able to make portaudio work with it too...
