Couple of places to double-check:

Is your soundcard mixer turned up for audio?

In BIAB, there are a few global volume settings. Some are for audio, and some are for MIDI. I know I've reduced the volume of audio to better match my MIDI synth; perhaps you've done the same?

Right-click on the Audio radio button, Volume slider

Opt., Preferences, Audio, Peak Limit Enable

And if MIDI is too loud, audio will seem too soft:

Opt., Preferences, Arrange, Normalize MIDI Velocities to ___

Opt., Preferences, MIDI Options, Allow Volume Changes
