And that won't change, because it is impossible to play back 16-bit sounds on this hardware (I know because I was the one who coded the current playback routine). The only way to deal with such wav files directly would be simply ignoring every other byte, which would be a waste of space. You have to convert the sound to a low-frequency (no point in making it more than 8kHz) 8-bit mono sample yourself before sending for this reason.
