title: Framework not found AudioUnit
body: <p>Been banging my head agains the wall for awhile now.
  My Xcode project went a little haywire while refactoring, and refused to build. I've squashed all the other errors, except one last linktime error:</p>
  
  <pre><code>Framework not found AudioUnit
  </code></pre>
  
  <p>I have the AudioUnit headers, the AudioUnit.framework is included in my project as it was before (Targets > Get Info > General > Linked Libraries > + ), but I cannot figure out why it does not work now. AudioToolbox.framework is also included.</p>
