This function starts playing a digital audio stream in polling mode. It allocates and empty stream buffer, and starts the Sound Device to play the stream. Sample data can be fed to the stream buffer with MIDASfeedSteramData. The stream will continue playing until it is stopped with MIDASstopStream. When a stream is being played on a channel, that channel may not be used for other purposes.
To avoid breaks in playback, the stream buffer size should be at least twice the expected polling period. That is, if you will be feeding data 5 times per second (every 200ms), the buffer should be at least 400ms long.
