I get this to work fine through something like
audioTrack.setPositionNotificationPeriod(bufSize/8);
audioTrack.setPlaybackPositionUpdateListener(this);
...
public void onPeriodicNotification(AudioTrack track) {
int frames = track.getPositionNotificationPeriod();
track.write(samples, 0, frames*2);
}
However - the callback is *Not* called from the thread that created
the AudioTrack (as it says in the documentation) but from the UI
thread, so you have to make sure you never write so you fill the
buffer or the UI thread will block.
