I\'m developing a project which has both audio streaming and playing audio from file. For audio streaming i\'m using AudioStreamer and for playing from file i\'m using avaud
I had the same problem, in more detail the error message was "hwiu" (hardware in use) or 1752656245. But I was using the MPMoviePlayerController before starting the audioStreamer.
I only had to stop the MPMoviePlayerController ([moviePlayer stop]) before releasing it in the moviePlayBackDidFinish method.
the stop should release some hardware componants.
I hope it helps
