title: ALSA: Full duplex C example?
body: <p>is there an example of a full-duplex ALSA connection in C? I've read that it is supported, but all the introductory examples I saw did either record or play a sound sample, but I'd like to have one handler that can do both for my VoIP-app.</p>
  
  <p>Big thanks for help,
  Jens</p>
