I'm listening to iTunes with etymotic earphones and I want to listen at a very low volume while I'm working. The problem is that the lowest volume level I can set from the keyboard is too loud and distracting, and adjusting down one level shuts off the audio completely. The earphones themselves have no adjustable volume control. I can get a little more low-volume range using the drop down vertical slider volume control, but not much. Is there a way to shift the whole volume range down, so that the keyboard volume control goes from silent to loud, instead of from silent to insanely loud, as it does now?
