Volume and speed problem.

While I play my downloaded music is will suddenly slow down the song. Why? Is it battery? the vol. does not seem to get very Loud even when turned all the way up. Why?

does it only do it when the display is off ?  Is your player almost full?  Download the update before it crashes.

The player is about 3/4 full and when the backlighting is on it runs fine, when it goes out,it slows down!

same thing happened to mine.  download the update http://forums.sandisk.com/sansa/board/message?board.id=express&thread.id=1143  before it crashes!!!  solved this problem on mine
