title: QNX Microphone sampling and speaker playback
body: <p>I am using QNX neutrino RTOS, I am new to QNX. I have setup my first project with some IPC messaging between two threads. </p>
  
  <p>What I want to do is have one thread as a microphone "driver" that samples input from the microphone and stores / sends it as PCM packets to another thread which plays it out of the speaker.</p>
  
  <p>So, are there any audio support libraries?, what is the best way to achieve recording microphone input and speaker output?</p>
