I've limited the volume range to -100..+12 dB in my latest patch now; this also avoids 4 chars in the status bar because the lowest value is replaced by the mute symbol. > The side effect free changing gets my vote, too.

Another benefit of switching to dB for volume is that it makes it easy to add clipping prevention at the app level, without needing knowledge about the specific DAC. We just need to make sure that current_volume + MAX(bass_boost, treble_boost) <= max_volume by reducing either current_volume (not good; old system for player & iriver) or bass_boost and treble_boost (better). Making this happen at the app layer also makes it easier to indicate what's happening.
