Try setting the following pref in your prefs file:

    OpenAudioDeviceOnPlayback=0

This should allow the core to open the audio device on engine startup. When
it does this it should be able to read the current device's audio volume and
use that instead of the default 50 for the first volume set. If you don't set
that then we don't create the audio device until the first clip is played; which
is the default.

If that doesn't help you, then are you willing to make code changes?
