Let me see if I understand what you are asking.

You have replaced the audio device that the platform uses with one
of your own correct, as outlined in the DSP Integration document?

You are asking when will resume() be called on your device implementation?

If that is the case, the you don't have to worry about it. The platform
knows the encoded pre-roll of each clip and knows how much audio PCM data
to push into the audio device (your code) before starting playback (resume).

So, it will make sure that your DSP decoder, and DSP audio device code
will have enough data before resume() is called.


Is that now what you are seeing?
