AudioUnitGetProperty results (FastDispatch)


  • Subject: AudioUnitGetProperty results (FastDispatch)
  • From: William Stewart <email@hidden>

We're seeing a number of applications assuming that AudioUnitGetProperty will always succeed. This is not a safe assumption to make, and in specific areas can cause crashing and other unwanted behaviours. The specific result we're looking at in this case is the FastDispatch property.

If you are using code that uses this property, please check the result. There is a good example of how to use this property with CAAudioUnit in the PublicUtility code
