PlaySound seems to play too fast with sampling rates like 8000 Hz, 16000 Hz, 24000 Hz ...
The speed seems OK with 44000 Hz, 22000Hz, 11000Hz, 5500Hz.
(It plays a little too slow with 48000 Hz.)
I didn't see that problem on Windows.
I suspect it stems from an SDL limitation:

Can anyone confirm that?
Is there a way around that?
