On some systems, the SDL audio callback is not called frequently enough (for example it requests 5ms of samples every 10ms), because the output buffer is too small. By default, we want to use a small value (5ms) to minimize latency, but if it does not work well, users need a way to increase it. Refs #3793 <https://github.com/Genymobile/scrcpy/issues/3793>
