OpenSLES | Destroy call not returning

[[e-mail]]

Hello All,

For following code-snippet


SLengine engine;
slCreateEngine(&engine, ...
.
SLObjectItf play = nullptr;
(*engine)->CreateAudioPlayer(engine, &play, ....
.
.
.
if (nullptr != play) {
(*play)->Destroy(play);
play = nullptr;
}


in which situation could the *Destroy* call be blocked on play object?

*Things tried so far:*

My initial implementation was creating and destroying, engine and play
objects on different threads. I assumed that, this might be the cause and
changed the implementation. Now, both the objects are being created and
destroyed on the same thread. But the problem still persists. I also have
an audio recorder object, which is being destroyed successfully.

Any help would be greatly appreciated!

Thank You

Can you please check the logcat around the time of Destroy, and see if
there is anything related?
In particular look for messages about possible deadlock or other warnings
or errors from your app or audio.
If so, please include those messages ... they might be helpful.
