v3 Audio Unit render block never called


  • Subject: v3 Audio Unit render block never called
  • From: Chris Adamson <email@hidden>

I finally have time to try to write a v3 Audio Unit (yay unemployment, I guess?), and while I have that big sample code from WWDC 2015 (iOSDemoFilterApp, et al), I’m trying to work from first principles, create a trivial unit in a trivial AVAudioEngine graph (input -> my effect -> output), and then build up from there.

Thing is: I can see the AUAudioUnitFactory and all my AUAudioUnit helper methods getting called, but the contents of the block itself are never executed.

Anyone got any tips for common things I might be overlooking?

I’ve also posted to the discussion forums: https://forums.developer.apple.com/thread/73691

Thanks!
