Audio problem... loud static

[Mark Swindell]

I'm trying to import some short button sound files into Rev 2.6.1, OS  
X 10.4.  When the mp3 files import  into the stack it's nothing on  
playback but very loud static, low pitched, like the sample rate is  
messed up, but it isn't.  Playing the same files from disk through a  
rev player sounds fine.  ITunes, QTime, other audio app, same files,  
all fine.  But both 2.6.1 and 2.7 give nothing but static.  What  
would cause this?

Thanks,
Mark
