Hi,
I know for removable audio devices, it is recommended to use StreamClass
instead of WaveCyclic (and PortClass).
However I have a WaveCyclic driver here, for a removable audio device, and I
was wondering if it was even possible to unload it correctly if I unplug it
while a stream is open. I always end up with a reference count of 1 for my
device object (I read that using OSR's DeviceTree).
I guess I'm not the only one who's had that thing to do. Does anyone know:
1) if it's possible to surprise remove a WaveCyclic driver without doing
anything fancy.
2) If not possible, which fancy thing I should do to make it work.
Thank you very much for any help!
