Internet resources...

Hi people. I made my first steps into the realms of QNX recently. I also want to learn audio driver development and audio app development, and want to target this specifically towards QNX. Can anyone point me to Internet resources for this type of development? I want to go to the core of my soundcards, so I can create weird applications…and I also want to meet like-minded people. Anyone know of forums which cater towards this sort of thing? Web-sites, mailing lists etc? Doesn’t have to be QNX specific - but this would be a definite bonus.
