title: How to register a virtual card to alsa from user-space?
body: <p>I'm developing a virtual device from the user space</p>
  
  <p>(using umview <a href="http://wiki.virtualsquare.org/wiki/index.php/UMview" rel="nofollow">http://wiki.virtualsquare.org/wiki/index.php/UMview</a>)
  so, i need to register my device to the system's sound cards list</p>
  
  <p>(I've never used alsa in a kernel module so I think that I need to call the snd_card_register() function)</p>
  
  <p>but I can't find a way to do that from the userspace...</p>
  
  <p>maybe I can write a syscall to do that?</p>
