I noticed that nodes are necessary for SysAudio to recognize minidriver as a
wave device. So I added 1 capture pin, 1 rendering pin, 1 line-in pin and 1
speaker pin. I connected them with two nodes (ADC and DAC). Everything works
fine, but:
1. On a W2K computer with no sound card previously installed SysAudio does
not register the driver as virtual audio device!(I only support standard
streaming interface)
I also have two more questions:
2. What is the proper way to restrict the number of filter instances created
by a device/filter_factory?
3. Can device be aware of wave device id assigned to it by SysAudio? How can
user mode application on W2K tell which device it accesses with WaveAPI? I'd
like one of my other drivers to provide device id to the user application
(possibly with cooperation of user-mode dll).
greetings
Konrad
