     On my XT clone (Fry's Electronic "Compustar") the speaker is driven by 
a little transistor that smoked when I accidently shorted the speaker leads
together.  Try looking near the speaker connector for a transistor or use a 
ohmmeter or a "light-probe" to find the PC(pun not intended) board trace
that connects to the speaker connector.  One side should go to power or
ground, I'm not sure which.

     I trust you've already re-seating the speaker connector and check for
broken wires at the connector(not always as obvious as it may sound).
