I am trying to play 16-bit mono 8 khz PCM audio. Using either
AudioQueue or RemoteIO AudioUnit, I get following results:
Simulator - 2.2 | Release - correct
Device - 2.2 | Distribution -correct
Simulator - 3.1.2 | Debug - correct
Simulator - 3.1.2 | Release - garbled
Device - 3.1.2 | Distribution - garbled
Essentially, 2.2 build works everywhere. 3.1.2 build works only in
Simulator Debug (have not tested Device Debug). Any idea what to look
for here? The garbling sounds the same with either AudioQueue or
AudioUnit and on Device or Simulator. Hard to describe. It is not
choppy like frames being dropped, nor is it hissy like white noise.
Thanks for any ideas.
Tim
