Comment 3 for bug 195760

Jonathan, that's demonstrably not true using Kubuntu 8.10. The increments are not even consistent in spacing, and change depending on whether you are turning the volume down or up:

100, 95, 90, 86, 81, 76, 72, 67, 62, 58, 53, 48, 44, 39, 34, 30, 25, 20, 16, 11, 6, 2, 0.
0, 4, 9, 13, 18, 23, 27, 32, 37, 41, 46, 51, 55, 60, 65, 69, 74, 79, 83, 88, 93, 97, 100.
