This is because -s -1 isn't a valid combination for wav (as per wav
specification); valid combinations include -u -1 and -s -2.

I'm guessing that this may be a bug in the audio driver that play is using.

Try play t.wav -s (and add a -V for verbose output), if that sounds okay, it
means that the wav is in fact correct, and the problem is that the audio driver
has a problem with unsigned.
