Sometimes the ALSA driver will report a very small amount of frames
available after a period signal. There is a bug in OpenAL 1.15 which
will crash the application if alcRenderSamplesSOFT is called with less
than 4 frames. And anyway, we shouldn't incur all of this overhead
just to render a couple of frames. So, just skip the rendering step if
we have less than a period of space available in the driver.
