Is the Drums track MIDI (yellow)? If so it sounds like you aren't hearing MIDI. First, go to the Options menu | MIDI Input/Output ports, and set all outs to "MIDI Plugins". Next, I would open the Plugins window (via Plugins tab of Mixer) and check what the Default Synth is set to. Usually it should be something like "Apple DLS Music Synth".
