Hi all,
I'm trying to debug a "crash report" from itunesConnect where my app
fails to launch in time (see below). This error has only been
reported (twice) on OS 3.1.1 (iPod touch). I believe it's a rather
rare event given how long my app has been out and the number of times
the app has been run, but I'm sure I've messing something up. I'm
using RemoteIO to playback PCM audio samples (no other audio services
are being used) and configure the audio session category for
kAudioSessionCategory_UserInterfaceSoundEffects. I have yet to
reproduce this error myself, and looking over the code am at a loss
what might be causing it. I know I'm not providing much detail, but
does anyone have any thoughts why an AudioComponentInstanceNew might
hang (or take a real long time)?
