the only way i have found to have more options for sound levels is to go into the tf3d settings and use the d-pad on the sound level sliders. hitting left (lower) will go further than right (higher) so you can eventually get to your sweet spot. i know that does not answer your question, but that is the work around i use. 3 bars on the htc volume control meter is too loud for an office setting IMO.
