Hi,
I'm new to audio driver development.
Now, I want to play CD sound from my driver via DirectSound - the data of sound
are from my driver instead from the real CD media. Some commercial software has
done this. After hacking them, I found they maybe call
KsSynchronousIoControlDevice to manipulate sysaudio.sys. While, someone on
msnews group told me this way is not stable. I think he's right but I really
want to know how those drivers do this.
There are so many professionals on this list. So, I think this is a right place
to put my post.
Could anybody here help me?
Regards,
Ray Yang
