enabling sound on mp3



I own three mp3 players, and I experience the same problem with all of
them: After I turn on the machine, there is no sound, although the
title of the selection is scrolling in the window.

I have to repeatedly press on the pause button before the sound
finally arrives...

How do I avoid this frustrating ritual and ensure that the sound
starts on start-up without any prompting on my part?
