Blender corrupting sound files!

I recently downloaded some .wav sound files off of the internet for use in a game I am making with blender. The sounds worked properly at first but after I saved the .blend file and reloaded it, the sound ceased to work. When I tried to open the sounds using Quicktime it gave me an OSStatus error-208. How can I get a sound file into blender without it making the sound files unreadable?

I am running Blender 2.5 on a Mac OS X 10.5.8

U r the lucky one; my computer plays all sound perfectly EXCEPT for Blender! I have tried everything; reinstalling drivers, Blender, etc. In your case, it maybe that u closed Blender before it had a chance to completely save your work. Has it happened a lot, or just one time? I’m using Windows XP - I tried Windows 7, and it worked great, but it is a RAM hog, so I had to get rid of it. What version of Blender are u using? I’m using 2.49b, and I have Realtek drivers.
It just corrupted the one file?

Here, maybe this will help out.

Sound works well for me, in a Linux OS!
