i am developping an application that takes use of an android phone microphone to emit sound at a 15-17KHz frequencies, every 3 seconds.

The problem is, after running for some time (more than 30 loops) sound doesnt go out at all, but the application still running normally.
I need this sound to be recorded for further operations.

is it because of some hardware support issues?
