I'm using SoundEffect in my app to play sounds...sometimes it works well and I hear sound; sometimes it crash at first stage or after several playings.
I've saved audio clip with 8000 rate and 16bit format (wav). The original one (44000 rate) got crashed more than its playing.
That is the crash output:
