I need to stream PCM data generated at runtime. So I have a thread with a loop

public void run() {
  while(...) {
    mAudioTrack.write(getPCM(), ...);
  }
}

Unfortunately this doesn't work. It seems it doesn't depend on AudioTrack buffer size. I want it to be very small to simulate sort of low latency behaviour (150 ms) so the user can dinamically change the PCM picked by getPCM()

int bufferSize = 0.150 * sampleRate * channels * bitsPerSample / 8;

However, I tried to increase the buffer size up to 100k with no result
