The waves work fine for me, using ALURE+OpenAL Soft and aplay (ALSA sound 
player) in Linux.

Since you mentioned problems with fread on Windows, also double-check that 
you're calling fopen with the "rb", or equivalent, mode. If you just use "r", 
it will open the file in text mode which transforms \r\n sequences into \n, 
and can mess up the returned data.
