Got a new computer, gave the old one to our daughter, now I'm unable to get the speakers to work. There isn't even the windows start up tune. Windows XP professional, SP3. I've checked the mute button, ok, when i go to admin tools, and under sounds and devices, I can't get anything from the speakers. The directions from the device help file says to push the play button, but none exists. The speakers did work on her old machine. I have a sound blaster card in there, things seem fine. what can i check next?
